1. Sheldon (Big Bang Theory), Michael Scott (The Office), Melinda Gordon (Ghost Whisperer), Chef Gordon Ramsey (Masterchef), Carry from (King of Queens) and Marie Barone, Ray's mother from (Everybody Loves Raymond).
2. I invited them because even though some are not the best or my favorite characters on these shows, they are the most dynamic and interesting characters.
3. I feel all of them with start an argument/fight at some point throughout the dinner. This is how it'll go
Sheldon would probably argue with Melinda Gordon. He's a scientist and she speaks/sees/talks to Ghosts. He will probably call her schizophrenic and try to logically wrap his head around her gift. She will probably cry.
Chef Gordon Ramsey vs. Marie Barone Ray's mother from (Everybody Loves Raymond). She would probably bring something that she baked that Gordon will probably criticize harshly (him being that angry British chef). She will probably defend herself and they will get angry and fight!
Michael Scott will probably annoy the hell out of everyone, especially Carrie from King of Queens. She will probably curse him out! He can be a bit creepy/ offensive and Carrie don't play that at all, she will put him in his place overtime!!!
I love this question, Had a lot of fun answering it
