Often the result of a pissed-off Godzilla, The Ultimate Showdown is a pointless century-long battle between famous characters, both realistic and fictional, resulting in awestruck civilians, hundreds of dead bodies, and a victorious (yet slightly suicidal) Mr. Rogers.
"This is The Ultimate Showdown of Ultimate Destiny. Good guys, bad guys, and explosions as far as the eye can see. And only one will survive, I wonder who it will be. This is the Ultimate Showdown of Ultimate Destiny."

Its where you get a heap of pedestal fans set up around you and you jack off into the fans so that it sprays all over you and you become Casper.

The option to have additional semen pored into the fans is also acceptable.
For instance you are in a warehouse and you set up a circle of fans for a Casper's Showdown

Guy 1: Dude, I was in a Shitter showdown with that guy from the Repair Center for 15 minutes! He finally left, but now he knows who the real Crapper Cowboy is!!!

Guy 2: Yea, he's intimidating. He finally got me to give up after about 10 minutes last week.

The round on The Price Is Right where a big wheel is spun and three players have already played their pricing games. The object is to come as close as you can to $1.00--WITHOUT GOING OVER. Getting the $1.00 (the 100) directly or in a combination of two spins (the two have to equal 100 or $1.00) awards $1,000 ($5,000 if a Million Dollar Spectacular). Landing on the green sections (5 and 15) during the bonus spin earns you $10,000 (previously $5,000) and landing on the 100 again on the bonus spin earns you $25,000 (previously $10,000). Players (and most often the host) can also be booed when they do not get the wheel around at least once.
