This will probably go down as one of the stranger sports-related wedding proposals in recent memory.
The Fresno Grizzlies held a Teenage Mutant Ninja Turtle night at their stadium August 2, and it appears to have been a huge success. One fan, whom you can watch starting at the 55-second mark, dressed up with his girlfriend and actually proposed to her while on the field.
The plan worked, as his girlfriend ended up saying yes.
Say what you want, but if your girlfriend is down to get engaged while dressing as a ninja turtle, she's probably a keeper.
