I was waiting at a bar once to collect a round of drinks.
Without any preamble, the stranger stood at my shoulder turned to me and said “have you farted?”
“No, I have not.”
His face was utterly incredulous as he retorted “what, NEVER?” and walked away.
I share that with you for no reason other than I was going to open with “have you ever had a great idea?” and that memory suddenly surfaced.
