I do too. Sometimes its happy drunks that are somewhat entertaining themselves. Other times its obnoxious drunks that you hope pass out or get thrown out.
Speaking on the former, in 07 I had season tix and the guys that sat behind me were nice dudes but would get completely hammered. During the Vandy game we were down for most the game and rallied in the 4th. One of the drunk guys went into cheerleader mode amd started going up and down the stairs trying to get our section fired up. At one point he took a little tumble before returning to his seat. It was pretty funny to me but others seemed annoyed.
