"Watch real baseball" joke

Top Ten Signs you're Not Watching a Real Baseball Team
From Late Show with David Letterman; Monday, February 20, 1995
You recognize batter as the kid who sold you a hot dog a couple minutes earlier.
Everytime a player slides into second, he busts his hip.
They keep shouting "Do over!"
When umpire yells, "Strike 3!" batter looks at him as if the dude's speaking French.
Try as they might, they just can't scratch themselves like professionals.
First base: Siskel. Second base: Ebert.
Game stops when some lady in a house near the stadium shouts "Dinner time!"
Players constantly adjusting each other's cups.
You overheard the coach yelling, "Run, Forrest, run!"
They play like the Mets.
