LOL, I love saying wise crack things back in situations :)
love the credit card comment!
I remember one time when we had a flat on the kid's bike and hubby was taking if off the rack---a person walking their dog says 'that stinks, a flat right off the bat on arriving' and hubby says 'man if I saw this on this bike I stole off someone's yard on the way down had a flat, I wouldn't have taken it!' then he mumbles the 'only kidding' after he gets the weird look!!
heck on vacation ya gotta have fun :)
