Twice when I've been out drinking have an older female sat alone all night, close to and staring at our group, then the first thing they say is "I'll let you know I actually have 3 PhDs and 2 doctorates, and I gotta say (some random bullshit)". Like "I don't think that joke you told two hours ago was funny". We just knew they would say some weird shit as soon as we saw them, the whole "I'm super smart" thing was just so much worse than expected.
