flash changing ties for thoughs times when your tie matches your bosses in the office.
or one of thoughs turn over signs.... i,m busy.... do not disturb.... coffee 2 sugars please.
how about showing your dad each ace one at a time turning it face down on the pack and tabling it then taking the next card for yourself.
at the end you have all the aces he has cards that say i love you dad, corny with cards.
