"This is great! I haven't had anyone to talk to about Rock Hudson movies in years!"
Rep. Ralph Hall (R-TX) really doesn't like gay marriage, so much so that he sponsored a bill that would have made it illegal for the Supreme Court to rule the Defense of Marriage Act as unconstitutional (because the Constitution is big on letting the legislature strong-arm the judiciary like that). This made it really weird when he showed up at a reception for the LGBT Victory Fund.
Everyone was very nice, but people quickly assumed he was lost, seeing as he has made himself a sworn enemy of gay marriage and all that. Hall was supposed to be attending another event in the same building for a fellow Congressman, and when he asked where his colleague was, the guests at the LGBT event informed him that he was at the wrong event. Said Hall, "At that moment I realized that this was not the reception I intended to attend, and I put down my glass, thanked the sponsor, and told him we would be leaving. Many of those in attendance were probably surprised to see me walk in, but were not surprised to see me leave quickly."
At 90, Hall is the oldest man in Congress and the oldest member of the House of Representatives ever. While this makes him extremely unlikely to support gay marriage, it also makes him pretty likely to wander into the wrong room and begin chatting up whomever is around. To be fair, everyone under 60 probably looks like a dirty hippie fetus to Hall, so we can't really expect him to tell LGBT activists and Republican staffers apart. They all listen to that funk-a-dunk noise music.
