There’s a Facebook page devoted to this knock knock joke, except it doesn’t have “The” in front of “Doctor”. Should this Knock Knock Who’s There The Doctor T Shirt have “The” in front of “Doctor”. I don’t think so, except that it throws people off the scent of the joke for a little longer as they’re staring at your shirt. So, that builds up a little comic tension, which bursts like a blister all over the faces of anybody within a 4-foot radius of this comedic discovery. And that’s funny.
Snorg Tees gets kind of sophisticated with their nerdy hommage.
