"If you're ready for a build server so pretty you could take it to the prom.."

The issue I have with this tweet is that it implies one would not take ugly people, regardless of gender, to prom and comes off as shallow. I also don't think it's a stretch to come to this conclusion as any other generally excepted positive attribute could have been substituted for "pretty" such as "awesome", "fun", etc which wouldn't have the same implications. No, I wouldn't take someone un-fun to prom, just like I wouldn't use an un-fun build server (or at least I wouldn't buy one).

Is there some context or interpretation I'm missing that implies otherwise?
