Last summer's Trios Fun League had a team called OddBalls. Very appropriate.
We called bowler #1 "Pogo". He was possum slow in starting his approach and, after delivering the ball, he'd start hopping around on his slide foot until it hit the pins. At that point, he'd stand still and stare towards the pins a bit too long. One night, Pogo began hopping all the way into an adjoining approach. The bowler on that lane finally had had enough. Anticipating Pogo's moves, he timed his own approach accordingly and slammed Pogo 6' past the foul line.
Bowler #2 was called NASCAR, because he threw a plastic Dale Earnhardt signature ball. Once on the approach, he'd get down on one knee and both hands to sight the lane, as if planning how to drive his ball around imaginary obstacles. In keeping with the ball's name, his delivery was always as fast and straight as he could manage. At the end of every series he was totally worn out, often in pain, and wondering why his high performance ball hadn't yielded strike after strike.
Bowler #3 called herself "Granny". She was 86-yrs old and suffering from dementia. Often very confused until Pogo and NASCAR could get her to pick up her ball, she was (sadly) the target of ridicule, too. One night, a young competitor, who had a pretty high average, started mocking her. Well, she managed to beat the jerk, and at the end of the series turned to him and said, "So there, smart ass!"
