yesterday ozzy called me into the bathroom with him, screaming he needed me to stay with him b/c there was a bug in there. 
what is it?  i asked.

it's a mast!  he says.

a math?  i ask, confused.

NO!  a MAST.  he says.

i dont know what a mast is.  oh, you mean a MOTH?  i say.

NOOO!  a MAST.  he insists.

ozzy, i dont know what a mast, is.  does it look a like an ant?  i ask, trying to determine what he was talking about.

yeah, he says.  a tiny ant, but it flies.

oh.  you mean GNATS!
