Just had the weirdest phone conversation

Probably a new fraud scheme.

Somebody from the area code of my old lab called. I normally don't pick up the phone unless I recognize the number. But I thought this could be K, Boywin, X or one of the old friends......

"Hello"

"Hi XXX, this is Dave."

"Uh... which Dave?" (I suppose most women have friends named Dave. Unfortunately for him, the only Dave I know is the grants manager here.)

"You don't remember me? It's Dave!"

"Uh, no." (I suppose most polite people would pretend they remembered and get on with the conversation while racking their brains about who Dave is. I am simply not very civilized in that aspect.)

"But you used to do nails, didn't you?"

"Huh? Nails?" (Are you talking about the kind that we pound into walls to hang pictures?)

"I mean, don't you used to get manicures and pedicures?"

"Uh, no." (Again, most women would have done these things at least a couple of times in their lives, but I am a stingy, germophobic slob.)

"Then I must have gotten the wrong number. But wait, you sound cute, are you single?"

"Uh, no, I am not single," (considered for 2 seconds whether I should inform him of the baby that is about to burst out of my belly) "Bye."

"Oh, I'm sorry I must have gotten the wrong number."

"Uh, Bye."

In retrospect there's scam written all over this. But I can't figure out how he could get any money off me this way.
