Back in the day, in the Navy days, I was in Portsmouth Naval Shipyard for a bit while we decommissioned our boat. Well, my buddy Mikey, he got the chlamydia from one of the young ladies up there and he's miserable, just miserable. So he goes to medical to get some help with this. Well, the shipyard there is over 200 years old and a lot of the buildings are make do with the space that they got; it ain't exactly intuitive how it's laid out. But anyway, Mikey goes to the medical building and walks sheepishly up to the desk and requests to see the doc. Well, this cute young thing manning the desk there asks him why. Well, as you can imagine, Mikey is a little embarrassed about his condition, especially in front of this young lady. So he says it's kinda personal. She looks quizzically at him, not quite understanding his apprehension, "hey we're all medical professionals in here, so...what seems to be the problem?". Mikey in two words - "I got VD".
She starts laughing. laughing out loud, hand over her face and laughing at him.
"This is the dentist office!" she says, "you gotta go upstairs for the doctors office!"
