"Mom - 'Wearing a tux.' Not 'wearing tux'. Tux is a singular noun."

"T-U-X, not T-U-C-K-S."

"Mom. We've talked about this before - it's short for tuxedo."

"Okay, now that should be tuxes. David was wearing a tux. David and Tom were wearing tuxes."

"Mom... I'm just trying to save you from embarrassment."

"Yeah, how about from now on you just say 'tuxedo' when you're around people you don't know?"
