Someone bumped his elbow while he was brushing his teeth.
A person who stays up all night wondering whether or not there is a dog.
They both abhor a vacuum.
Because it takes more than 35 patients to make a full set of teeth.
He ate a Pb and j sandwich I'd tell you another but all the good jokes argon
Sorry, my fault.
Pardon me.
Two pirates.
A FSSSSSHHHH
A chair, a bed, and a toothbrush.
Because it's humerus.
