The individuals pictured below are LOSERS!
Well, the one on the left has lost his senate seat. The one on the right lost her bid for the DNC nomination for president. You could reasonably say that they're losers. Not sure about the one in the middle since I don't know who he is, but I suppose he has lost something as well.
I guess that wasn't your point. There are about a billion "losers." John Edwards, Mike Huckabee, John McCain, Jesse Jackson, etc., but we don't put pictures of them in our signatures. I don't think it's immaturity though. We talked about this in one of my undergraduate classes. Sociology, I think it was. Apparently there are such people as thrive on negativity. Nixon was this way, apparently. And we contrasted them with positive sorts, like Reagan. I don't think Nixon (or BRTD) will outgrow this condition. It's just part of their personalities. I'm guess you're a very positive person, like Reagan and Clinton, based on your signature, but that doesn't make you any more or less mature than BRTD.
Hell, some folks put girly pastel ponies in their sigs. It doesn't mean that they have the personalities of eight-year-old girls, but it probably says something about them. Signatures are telling. My son's first-grade teacher has some cheesy educational quote from Tom Osborne in her email signature. I don't go in for signatures, and that's probably telling as well.
