I wish I could play little league now. I'd be way better than before. - Mitch Hedberg
Growing up as a twin people would ask us if we ever pretended to be the other one or went on dates for the other one or any other twin-related pranks. And for the most part, the answer was no, especially with dating. It wasn't always easy to get a date in the first place, so neither one of us was going to pass up the opportunity to actually go on the date.
But there are some exceptions. In Jr. High band we once switched instruments as an April Fools joke. Neither one of us could play the other's band instrument very well, but sadly, the band director never caught on. Perhaps we weren't that good on our own band instrument either.
And then there was little league baseball. One year when we were around 11 or 12, I was one of the pitchers for our little league team. I wasn't great, but I could get the ball over the plate most of the time, which is pretty good by little league standards. And unlike the little league pitchers today, I wasn't damaging my arm by trying to throw sliders and off-speed pitches, primarily because I didn't know how.
We had two games per week, and pitchers were only allowed to pitch one game a week per little league rules, so Ron and I alternated games. However, Ron had control issues ... with his pitching ... so almost the entire season I pretended to be him on his pitching days. We didn't switch jerseys, and I never said, "I'm Ron." I just went to the mound and pitched.
No one ever caught on as far as we knew, although one opposing coach asked me before the game, "Didn't you pitch earlier this week?" So, Ron pitched that one game, but I pitched the other 15. I believe I finished the season with 10 wins, 4 losses, and 1 no decision.
Of course, since "Ron" pitched half of the games, I could say I was 8-0.
