Laughing so hard that tears start coming out of your eyes means that something was really funny. When you are sitting completely alone a couple hours later at your computer and start thinking about it again and then laughing so hard about it again that tears start coming out of your eyes again, that means that something was really, really funny. Such was a chain of events at karaoke this evening. It was certainly in the class of had-to-be-there-funny-things, so I won't even try.
People are surprised that I much enjoy karaoke, or at least those people who know me well enough to know that I have no musical aptitude whatsoever (none, zip, zilch, nada, I've got a half-octave range, max, and I have trouble even clapping along with other people if the clapping is anything beyond a steady and easy comprehended beat--that clap, clap-clap, clap-clap, clap stuff, no chance). Three rules for increasing your enjoyment of karaoke if you have low musical ability and showpersonship skills: (1) sit up front; (2) cheer wildly for people you know, but cheer at least as wildly for strangers you don't know if they seem like they have any sense of fun, which most people who get up front for karaoke probably do; (3) tell all such strangers that it is the birthday of someone at your table.
