Well put. Self-deprecating humor certainly meets your criteria!
Here in Boston we still make fun of the accent even though it's not as common as most depictions would make you think.
That said, I would wager that the getting laid jokes are not (as?) funny to most of us who have been here from the beginning (so, at least for me, someone around 40 years old -- see my UID!) and at this point no sex would either be:
- 1) really sad
- 2) ok, just between relationships!
- 3) not an issue as our significant other is static at this point.
