Yesterday my family had an early Thanksgiving. In the evening, we sat around and played Catch Phrase. It was my Grandpa's turn...

Grandpa: the spewer in Montana
The timer: bzzzzzz
Aunt Rhonda (from the other team): Spear in Montana...Devil's Tower?
Dad: Devil's Tower isn't in Montana, it's in Wyoming
Aunt Rhonda: Doesn't mean he knows his geography
Dad: Maybe he said spewer
Aunt Rhonda: Old Faithful!
Granpda: That's it!
Me: I thought Old Faithful was in Wyoming?
Everyone (except Grandpa): It is
Grandpa: Bull
