Title: Rocky Balboa

Doctor: You have B-7 deficiency.

 

This joke explained: B-7 deficiency is a rare vitamin deficiency. Med students have to memorize that avidin, which is in raw egg whites bind very strongly to B-7. This can prevent it’s absorption. Rocky balboa downs a bunch of raw eggs every morning. As we all know jokes that require a ton of explanation are extra funny… right? =(
