Cups and balls or a chop cup are both great If you miss for busking. A ton of buskers do it, and it isn't coincidence.
I do it to close my set, and one of it's strengths is that it's modular. People can start watching partway through (as happens in busking), and they can still get it. Balls vanish, teleport, appear, etc. and you don't need to see the beginning to get it. If you miss the first half of a triumph routine, and only see one card reversed in the deck, it's not terribly strong. If you miss most of a cups and balls routine, but still see balls vanish replaced by lemons, you've still seen some strong magic
Also, there are spots in it great for hat lines.
