Lick your hand and see the spit evaporate. Love may be blind but marriage is a real eye-opener. My mind is like a steel trap - rusty and illegal in 37 states. Never do card tricks for the group you play poker with. No one is listening until you make a mistake.
Nothing is fool-proof to a talented fool.
On the other hand, you have different fingers. Order pizzas for all your friends to be delivered unexpectedly to their homes. Order taxis for all your friends that aren't going out. Paint your windows. Plan to be spontaneous - tomorrow.
