[The Megan 2207]

Mentor: We need someone to paint the team number on the bumpers!
Me: I'll do it!

10 minutes later...

Me (holding bumper with team number painted on it): I made an oopsie.
Mentor: It looks fine to me...
Me: (turns bumper upside down): It goes this way.
Rest of team erupts in laughter.

It's the front bumper, too. The mentors thought it was funny, so we left it that way. Anyone attending the Minnesota Regional, look for the team with the upside-down front bumper (unless it doesn't pass inspection and we have to fix it really fast).
