Origami

I was eating lunch at a nice, small, hole-in-the-wall Vietnamese joint the other day. Good food, a Banh Mi sandwich. Anyways, I was friendly flirting with the waitress and in between her stops at my table, I made an Origami rose out of a napkin. She came by and handed me the bill with no rush to leave. Seeing that I had her attention, I paid the bill, no change, and gave her the origami rose with my name and number attached.
Sounds dumb? Maybe corny? It worked. She called me that evening. I've used the origami rose, weather in napkin or dollar form, many times with positive results.
Even though it sounds corny to me, it works. Do any of y'all have something you say or do, in the civilian or sc world, that might sound dumb, corny, schtick,etc., but works? Don't be shy. Let it out. Oh yeah, this isn't some PUA type tactic.
