Sadly they didn't teach us much about sex and reproduction except for oogenesis and spermatogenesis and the whole menstrual cycle thing. Picture of elephantiasis during micro was probably the most shocking/entertaining thing we had.
oh well... here's a dentist joke i recently read:
A dentist and an OBGYN are on a tour together. A random tourist from another group comes up to the dentist and says, "Doc, hi, it's me, remember??"
Dentist goes, "uhm, not really, can you open your mouth please?" The dentist takes a look, "oh, it's you! How are you and the kids?"
Afterwards, the OBGYN says to the dentist, "guess it'll be a lot harder for me when I forgot what my patients look like eh."
