I did Born to be wild by Steppenwolf at a X-mas party in a group of 6 with the CEO. Had been drinking the whole drive over (free party bus for the ride) and more at the party so I was pretty tossed. During the chorus I had the mic in front of me and was yelling out "BORN TO BE WILD!", but when I got to the word, wild, a massive belch decided it wanted out. "BORN TO BE BLAAAARRRRP". The whole room burst into laughter and it totally disrupted our performance, but it ended up being the high point of the party.
