The Adventurous BILL GAME!! To play this, you first pick a common name, like BOB, BILL, JOE, or STEVE. This is going to be the “magic” name for the night.
When you get to the bar, have all the girls try to collect the most signatures from people with the “magic” name at each of the places you go. Every time one of you gets a signature, they get to make all of the other girls take a drink.
If you’re at more than one bar that night, there would be a winner from each of the places you go. At the end, the losers from each place all have to drink, or have to buy the winner a drink at the next place. Whichever your fancy.
Then at the end of the night, there would be a grand prize winner that could win a certain funny prize like an Out of Control Ribbon or a Pecker Whistle.
You could make it more challenging by deeming the name, WILLARD, or something more uncommon like that, but you also chance things not working out so great. I guess you could have a regular name for the “magic” name, and then agree upon a more difficult “bonus” name that would score 1.5 points instead of 1. It’s up to you. Have fun!
