Confused...

[rebbonk]

After returning home from an examination, a young blonde woman phoned her Gynaecologist and asked, "Doctor, would you see if by chance I left my underwear in your office?"

He looked in the examining room, returned to the phone, and told her, "I’m afraid they are not here.”

"Sorry to trouble you, doctor," she said.

Spoiler:

"I’ll try my dentist."
