At least everyone around cheered for that little cleaning lady when they got her over the barrier and back. I feel like it was a combination of "Hooray, no puke!" and "Hooray! She's taking one for the team to clean puke when she doesn't want to!"
Anyone else notice when Trent started singing random bits of "Closer" during "All Time Low?" I recall him saying quietly, "You get me closer..." and "You let me violate you..." alternately a couple times. Another awesome little twist you can only get from the live show.
