I hate it when someone makes a joke relating to my Basilmarket username like "for someone named smartguy11, you're not very smart". OMG wtf?! We're all quite aware that my username is "smartguy11", but in what case would a name be relevant to what I'm saying?! I've heard this crap a million times. Stale wit is not going to make you appear any wittier. -_-
And most of the time, the joke is a negative one (like the one in my example), usually based completely on the poster's opinion. Sorry, but last time I checked, I'm not "AgreesWithEverythingEveryoneSaysGuy11".
