Quasi-gaffes off the top of my head
Rand has done pretty well about not putting his foot in his mouth, but when you're mouth is running for eight hours you're going to say some funny things:
five-foot-away photo of someone in a swimsuit (failed joke)
labored pronunciation of Italian journalists for WIRED
"Fruit of the Loom stock" not in reference to tighty whities
certainty and property
I'm pretty sure that last one is the part of the title that comes before the colon of a thesis written by an overly serious poly sci major from George Fox.
