In highschool I was in shop class with some idiots that were messing around with a running table saw. The teacher saw the obvious kick back danger and swooped down on them with an angry "Hay! Do you want to have kids?!". Before I could stop myself I said "Damn, you should at least buy them dinner first."
He was not amused, but I am still proud of the one time in my life I was quick witted enough to come up with something funny on the spot. It's been so years 30 years since, and nothing has come close.
None of those are good options.
