My favorite warning was on a can of peanuts. "Warning: may contain peanuts."

Seen on an industrial size washer in our local laundry establishment was the (large lettered) sign: "Warning: Do not put any person in this washer."
My Dad worked at a laundromat when he was in highschool. There was one washer that was walk-in. My Dad's good friend who also worked there, accidently turned it on while inside (he forgot to turn off the safety switch). When Dad discovered him, there were no chunks left large enough to identify.
Sorry to gross people out, but that is an important warning.
