So far, the fourth season of How I Met Your Mother has given us a lot to laugh about.  From Lily (Alyson Hannigan) and Marshall (Jason Segel) contemplating having a baby, Robin (Cobie Smulders) becoming Ted's (Josh Radnor) roommate to Barney's (Neil Patrick Harris) failed attempts to tell Robin he loves her.  Soon, however, the show will be returning its focus on Ted's love life when Laura Prepon guest stars as Ted's love interest.

Perhaps best known for her role as Donna Pinciotti, longtime girlfriend of next-door neighbor, Eric Forman on That '70s Show, Laura Prepon has signed on to play Ted's once (and possibly future) girlfriend.  Following That '70s Show, which ran from 1998 to 2006, Prepon worked on movie The Chosen One and then returned to the small screen to join the cast of the ABC drama October Road, which was eventually canceled by the network shortly after its debut.  No word yet on when she'll be making her debut on the CBS sitcom but it has been confirmed that she'll be appearing in at least five episodes.

MTV has a string of projects underway for the summer and fall seasons, including a half-hour scripted comedy series from Wilmer Valderrama.  Best known for his exchange student role as Fez on That '70s Show, the 28-year-old actor has had a long-standing relationship with MTV as he created, executive produced and hosted the network's trash-talking competition program, Yo Momma.  Now, he will once again attempt to turn a pilot into a hit series with his new project called Baby Dolls.

Given the day, it seems only appropriate that we would pay respect to the most laid back, easy-going group of all: the stoners. April 20 is as close as we come to having a Nation Weed Smoking Day in this country, so what better way to celebrate here at BuddyTV than to reflect on our favorite pot-smoking television characters. Well, I imagine you could think of one or two better ways.

For this list, we've put together five of our favorite television characters with reefer madness.  Sure, there are many characters who've experimented, such as Seth Cohen from The O.C. or Ross on Friends, but for this list, we wanted honest-to-God, red-blooded, bong lovers.  And indeed, we've found characters who all have a need...a need for weed.

Disco may be dead but the funky decade full of polyester and eight tracks lives on when That ‘70s Show season 8 boogies its way onto DVD April 1 from Fox Home Entertainment and Carsey-Werner.

Following the departure of both Eric and Kelso, the fun-loving friends of Point Place, Wisconsin are forced to recognize times are a-changing. Hyde returns from Chicago a married man while Jackie and Fez explore their relationship and move in together. Donna starts a new relationship and Jackie lands a job at a television station as an assistant to a psycho boss. The whole gang manages to reunite for a final bittersweet farewell to the decade that has brought such hysterical hijinx and overall mayhem.

BuddyTV has five copies of this eighth season of That '70s Show to give away. Here's how you can win a copy:

Wilmer Valderrama catapulted to stardom on That ‘70s Show as Fez, who was named by the writers of the series as an acronym for Foreign Exchange Student.  As an immigrant, his distinct accent, as well as his ambiguous country of origin, was one of the longest running gags on the show.  Though his raging hormones attracted him to various women, he was mainly infatuated with Jackie Burkhart (Mila Kunis), whom he worshiped like a queen.  After all the barriers, heartaches and struggle, Jackie finally validated her feelings for him during the finale when she realized that he had all the qualities she's looking for in a man, sealing his painful longing for her with a kiss.  Despite the end of the series, the 27-year-old comic remains to be an active actor with his voiceover works and upcoming movies.

Danny Masterson was best known as Steven Hyde on That ‘70s Show. His character had a signature wardrobe consisting of sunglasses and t-shirts with musicians on them such as Led Zeppelin, Jimi Hendrix and The Rolling Stones.  He was the best friend of Eric Foreman (Topher Grace) and often spent time with Michael Kelso (Ashton Kutcher) and Fez (Wilmer Valderrama).  As the rebel of the group, he was noted for his wiseacre jokes, conspiracy theories, radical antics and love for marijuana.  These days, the 31-year-old actor is working on a comedy and a crime-drama movie.
