What would you "not do in a million years"?

I hear this saying at least once a week…mostly from my employees AND kids, so what is it you wouldn’t do in a “million years”??

Did you ever say this or have it said to you?? Why not do it now??? What was the big deal? Were you afraid of getting your new clothes dirty? Couldn’t get you drunk enough?? What was it that you or someone said they wouldn’t do “in a million years”?
