Christmas Dinner cancer humor

Epic hilarious Christmas dark humor moment:

Mark was making microwave popcorn for the movie, face nearly pressed against the microwave door, watching it pop.

Wendi says: "Mark, get back so you don't get a brain tumor or something. ......oh, wait....."

Mark gives her a mischievous grin, and says "Ha, ha, ha" and then starts laughing, then we all bust up.

"....never mind, you already have one. Go ahead," says Wendi.

Mark thought this was super funny....lol, go Team Mark!

Merry Christmas!

EDIT: Just to clarify, there were a lot of other things going on at the moment this happened, Wendi did not mean to say it that way, it just came out automatically and could have been anything.... totally accidental. She was a little worried some might assume she did it on purpose, so just clearing that up. ;)
