My favorite t-shirt is my 8th grade wrestling shirt that says "Knight's Wrestling" on it, which I am proudly wearing now. It was the only decent athletic shirt I got in middle school, but it is actually very awesome, and, coincidentally, all of our sports teams rocked that year (we used the same design for several different events). Many were undefeated (football, wrestling, softball, vollyball) and the basketball, track, cross country had phenominal records as well.
But alas, I didn't have the stuff to continue in HS, although doing that meant a year-long recruitment attempt from the team for anyone who they remembered from middle school...
