Last night was "TMNT Night" at the Fresno Grizzlies minor league baseball game. It's only natural, then, that a dude dressed as one of the Turtles would propose marriage on the field during warmups to his girlfriend who was also dressed as a Turtle, as you can see in the video.
This is just heartwarming as hell. This kind of thing is why minor league baseball is so good; they had free pizza and TMNT versions of the team jerseys to auction to fans and the "actual" Turtle bros themselves even showed up.
I hope this couple knows they have to do this ninja turtle thing again at their wedding, though.
