When you’re a stand-up comedian who travels a lot, you see some odd things, as Keith Alberstadt will tell you. “I was in an airport,” he tells an audience. “And a lady was trying to locate her son who had wandered off. That’s got to freak you out, right? But I couldn’t help but laugh because I heard her shout his name: Marco. I don’t think that’s fair. You shouldn’t be allowed to name your kid Marco and then lose him. It’s child abuse.”
