I've taken to pronouncing the Java generics wildcard character as "huh?".  So that:

List<? extends Comparable<?>>

is pronounced "List of huh? extends Comparable of huh?".

I've also been doing the equivalent of finger-quoting when pronouncing these expressions, doing angle brackets with my fingers on either side of my head as I say the stuff that's in angle brackets.

I simply must work these into a presentation sometime...
