All of them are classic, but my favorite (can't remember the name) is the one where you have to place price tags on 4 items, then race back and pull the handle on that machine that tells you how many you got right. Then if you had less than all of them right you have to run back and rearrange the ones you think you got wrong, pull the handle again, etc.
Cliffhanger always rocked my boat. The yodeling music was really out of this world. Plus, win or lose I was entertained. I liked seeing him fall off and I love bouncing titties.
