So we were did a lab on DNA today in bio, and it included isolating your own DNA. David and I did it together as usual (much to his dismay) and he was doing the actual "isolating" part while I was cleaning.
David: Hey it's Elaine's DNA!
Kathleen: It looks like sperm!

*SIGH* and if THAT wasn't enough.

David: Hey Elaine, Kathleen thinks your DNA looks like sperm.
Elaine: WHAT?
*30 seconds later*
Elaine: Hey can I see my sper--DNA I MEANT!

Okay I MEANT DNA but like... Kathleen's little comment was playing in my head.
So Hubert starts tormenting me about it, "OH ELAINE, you have SPERM! I KNEW Yogin was the girl in the relationship!"
me: Just because you don't have any Hubert!
