Let me give you a recent example... based on true events.
The intros are going around in a circle and everyone is new. The first kid starts, "My name is Robert. I am from Germany," Already more interesting than me. "And I have been to every country in Europe." Thanks Robert you have set the bar extremely high.... "My name is Chris and I am double majoring in economics and finance, and something interesting about me is that I play the accordion." I can play the Mission Impossible hook on the piano with one hand... I need to think of something fast. Maybe they will come back to me if I pass? Who passes on this? Losers do. "Hi, I am Ashley. I go to school at the U. And something interesting about me is... I uh....Oh good, she is struggling too! Good. Please think of something so dull... every two years I cut all my hair off for locks of love. I've done it since I was eight. Are you freaking kidding me.
At this point I am racking my brain for anything. I peed my pants in second grade. The only high school prom I went to was with my sister. I do not mind eating onions whole. I suck at math, all of it. NO! NO! NO! It isn't "tell me something weird and embarrassing about yourself."
It is somehow my turn, just in the same way that 6 is after 5. "My name is David." Hold on, you just started. I thought you were going to crawl under something...great... well don't stop now. GO! Say something from that dumb mouth..."I am from a small town in Nevada...." Clap for the kid from Nevada everyone...
"Yeah... I am Jeffery, I... I am from Nevada? That is what you spewed from your lips. Nice brain drain.... and I built my own car from junk yard parts. Turning my ears off now. Time to think of interesting things that you could lie about.
After I am home I think of several good answers. I have killed an aligator, I have chased wild cows, I fought as the main event for a school sponsored and organized fundraising boxing match, I have directed and starred in my own movie productions, my favorite food is home made soft tacos, my right ear is a half inch longer than my left ear, or even I have caught a seagull while wake-boarding.
Do not find yourself in a bind like mine. Think of things beforehand. Have a list in your mind.
