Dr. Sheldon Cooper from Big Bang Theory is talking to Mr. Spock from Star Trek. Chuck (from Chuck) is talking to Sydney Bristow from Alias. Buffy the Vampire Slayer is attempting to stake Bill Compton from True Blood. JD from Scrubs is trying to tell Dr. Gregory House from House, M.D. a joke, it appears, while Liz Lemon (30 rock) appears to be tripping over his cane. Dr. Tobias Fünke from Arrested Development seems to be watching River Tam from Firefly. The Doctor from Doctor Who is using the sonic screwdriver on Walter White from Breaking Bad, while just in front of them, Sherlock Holmes from Sherlock is spilling his wine onto Dexter's shirt. Don Draper from Mad Men sits next to Barney Stinson from How I met Your Mother, who also share the couch with Quinn Fabray from Glee and Jeff Winger from Community. Dwight Schrute from the Office is being seduced by Cylon number 6 from Battlestar Gallactica. Rick Grimes from the Walking Dead has his pistol drawn in the corner. The guy in front of the tv is Jack Shephard from LOST.
The pets I'm unsure - they could be from Frasier (Eddie, dog), Sabrina (Salem, cat), and LOST (Vincent, dog).
Of, in rijtjes:
Back row, left to right: Dwight (The Office), Caprica 6 (Battlestar Galactica), Dr. House (House), JD (Scrubs), Tobias (Arrested Development), Liz Lemon (30 Rock), River (Firefly), Jack and Vincent (LOST), The 11th Doctor (Doctor Who), Walter (Breaking Bad), Rick Grimes (Walking Dead).
Middle row: Buffy (Buffy the Vampire Slayer), Bill (True Blood), Jeff (Community), Quinn or really any other cheerleader from (Glee) and honestly could be Claire from (Heroes) if you'd prefer, Barney (How I Met Your Mother), Don Draper (Mad Men), Dexter (Dexter), Sherlock Holmes (Sherlock).
Bottom row: Sheldon (Big Bang Theory), Spock (Star Trek:TOS), Chuck (Chuck), Sydney Bristow (Alias).
Window: TARDIS (Doctor Who), USS Enterprise (Star Trek), Galactica (Battlestar Galactica), Serenity (Firefly).
Also, the dog is sorta supposed to look like the dog from Frasier, and the cat is sorta like Salem from Sabrina the teenage witch.
