Take care when yawning

The tongue is a muscle and can, like all muscles, be pulled when it is stressed. I found that out this morning when my mouth exploded in an especially ferocious yawn. A sharp ache lodged itself deep in the back of my poor tongue. Hurt like a motherfucker. So, as I was driving to work, I thought about maybe developing a regular tongue-exercise routine in order to avoid that painful experience in the future. Seven middle fingers and eleven dirty looks later, I stopped. Good thing they couldn't tell I wasn't wearing pants.
