Hey Jimmy Kimmel, I gave my kids a terrible present
OK, we thought of something that might be meaner than stolen Halloween candy: getting a half-eaten sandwich for Christmas. We'd say they should go on Santa's nice list for putting up with this, but some of these kids had pretty major meltdowns.

Cousin Sal and Jimmy Aunt Chippy sonogram prank
It's cruel enough to call Aunt Chippy "as sweet as a shot glass full of gasoline," but Jimmy took advantage of how gullible she can be, too. In her very first sonogram viewing, the "baby" made a pretty rude hand gesture...and did some jumping jacks.
