Look at my watch and in a thick southern accent:
"Well wouldn't you know it boys, it's three o'clock. The ol' ball n' chain will have my supper ready in no less than 15 minutes. Now, I'd love if you could join me, but me ma's in town and she doesn't like your kind, she think's you're too rough fo' her middle class origins. I'll have to catch up with you later on, maybe grab a drink in the ol' local. We'll be seeing you boys, goodbye."
Given, it's more than one sentence, but it'll be some weird last words if'n it doesn't get me out of that bad situation.
