when i was 14, i saw lyle lovett in concert. he had a drunken heckler, and dealt with her like a true pro. ignored the first two comments, joked that she should come up on stage and dance for us ("I'LL DANCE TO WHATEVER YA GOT" came the reply), and then went back to ignoring her. i heard a guy behind me somewhere mutter "i think it's past your bedtime..." har har. nothing worked.

finally i yelled "shut up!", and the whole house applauded. that worked.
