Harvard band appears to spell 'penis' on the field vs. Penn (PHOTO)

It looks like these Harvard band members may need a refresher course in spelling — or do they?

During the Crimson’s game against Penn on Saturday, the home band appeared to spell out the word "penis" during their routine.

While certainly amusing, this may not have been intentional.

It's possible that the band was trying spell the word "Penn" and just got mixed up or they thought they were playing Penn State and just ran out of trombone and tuba players.

Either way, it's still funny.

The real shame? Nobody was in the stands to see it.
