Um, I think he said worst gig, not best.
A couple years back, I was talking to Rachael Price, the singer with Lake Street Dive. (A great band, by the way.) And she told me a story about a bar gig the band played when it was first starting out. She was singing and a woman jumped onto the stage and motorboarded her and yelled, "Motorboard, y'all." And then jumped off the stage. I asked Rachael when she did and she said she just kept singing.
