Steve Kirsch has archived a humorous listings of things to say when you’re, um, losing a technical argument. A few of my favorites:

• Oh, I played with that approach back as an undergrad. Got a D, too.
• Yeah, or we could all just plink away on Amigas or something.
• I like it, but it is too point-oh for my tastes.
• We need this to fit on a single floppy.
• I remember that IBM had a project to do that back in the 70s.
