Please don't drink out of my glass.
I don't mean to be crass
but please show some class
and refrain from drinking out of my glass.

Please don't drink out of my glass.
Sorry to be so unkind
but I don't want to find
your saliva, alas.
So please don't drink out of my glass.

Please don't drink from my glass.
I know it's not social
to be going so postal but your sipping is driving me crazy
and now that my judgment has grown rather hazy
I just might give you a swift kick in the *** so please!
Don't drink out of my glass!
