Well, start off with ordering a sub (hoagie, grinder, big ol' meaty sandwish) with mayo on the side. Put the mayo (in it's plastic container) on the countertop. Forget to use it and leave it on the countertop overnight. In the morning, while drowsy, let your shirtsleeve catch the container and flip it.
Judges only awarded me a 7.8.
I would have given you a higher grade, tD. I've never done that. Probably tomorrow I'll do it. I've done that with milk, though. But mayo is more messy.
