Mbo, I didn't mean to downplay the seriousness of the affliction, it just fit well that way. You raise a good point, though. Medically related humor is always tricky because you're dealing with people's pain and distress. Unfortunately, medical training is stressful and medical students often tend to attack others' weaknesses when they feel inadequate. I'm afraid it's part of the human condition--it's certainly not limited to medical students--and I confess to doing my share. (That's one reason I don't perform my VD song anymore.) Much of what is considered humorous by some people is offensive to some people in some contexts at some times. But we keep muddling through, hopefully with good humor, and can try not to offend but to amuse.
Sorry for the sermon...it just broke out.

Aloha,
Mark
