The North Dakotan goes to the baseball game.

There once was a North Dakotan who went to a Detroit Tigers baseball
game and he was enjoying his first beer and hot dog when a man behind
him yelled "Hey, Ernie!" The North Dakotan stood up and turned around to
see who was calling him, but saw no one he recognized so he sat back down.
A minute later, the same guy yelled out "Hey, Ernie!" The North
Dakotan again stood up and again saw no one he knew, so he sat down again.
A half minute later, he AGAIN heard, "HEY ERNIE!!!" The North Dakotan was
upset with this guy, so he stood up, turned around, and yelled out as loud
as hecould..."MY NAME IS NOT ERNIE!!!!!!!!".
