Lets run through the F.A.S.T. checklist:
Face drooping: No, more of a laughter rictus.I was not expecting the answer to the headline question to be this pithy.
Arm weakness: maybe-I have fallen on the floor and seem to be losing control of some bodily functions.
Speech difficulties: can't talk, actually, can't breathe.
Time: to call for help
