"Big Bang Theory" star Jim Parsons opened "Saturday Night Live" with a song about how actors — in real life — are nothing like the famous TV characters they portray on-screen.
"People have a hard time separating you from your character," explained Parsons. "I am not like Sheldon. I am not a scientist. I do not speak Klingon. I do have a male roommate, but I assure you it's a vastly different arrangement."
Parsons then broke out into a song titled "I'm Not That Guy," referencing iconic TV characters from the past and the actors who played them.
"In the 90s there was Urkel, he made Friday nights a blast, but Jaleel White — he's a full grown man— who could probably kick your a--."
