Some of you may recall how, in Girl in Lovers Lane, Dr. F and Frank presented their concept of evil baseball promotions. So how about we add our own ideas.
I propose Chocolate Bar Night, where everyone gets a free chocolate bar. Now you might think to yourself that there’s nothing evil about that. Well behold the subtle working of my talents! Those “chocolate bars” are really Ex-Lax. If you think the restrooms at your local stadium are disgusting now, just wait.
“Sober Night” where you have to watch a whole Baseball game, without drinking.
Or is that too evil?
Free ticket night. 
Joe Namath Night!
In honor of Broadway Joe, the players would skip their usual uniforms and only wear… umm… nevermind… 
“Frank! ‘Poopie night’.”
“Bite me, it’s funny!”
“I’m not saying it’s not funny… What, are you going to give the kids poop?”
LOL
I had a sober night for my last outing to the ballpark (probably the first time ever). I was taking my granddaughter to her first baseball game, and wanted to make sure I was sober for the ride home. The Cardinals clinched a wildcard berth against the Brew Crew that night, so it was actually worth staying sober for.
“Vuvuzela Night.”
'nuff said.
Free Pet Turtle Night, because nothing says love like Salmonella. Get ready for ongoing disasters in your bathroom at home, too. o_0
I thought that was roast beef on a hard roll.
Pepper Spray Night.
All fans receive a free sample of pepper spray to the face.
As someone who, due to origins of family, is a Pittsburgh Pirates fan (albeit casually these days), this is, indeed, evil and arguably sadistic.
Meat Re-Animator Chicken Dance Night. All kids get a shiv.
Served with a Kenny-shaped after-dinner mint on its “back.” 
A bobblehead night, but for the owner of the team. Truly something no one wants or asked for.
Overripe Durian Night
“It’s a pungent night here at the stadium…”
Hard rolls are friend to all children.
