A man decides to take the opportunity while his wife is away to
re-varnish the toilet seat (which was made of wood). The wife comes
home sooner than expected, needs to use the toilet, sits, and gets
the seat stuck to her rear. She is understandably distraught about
this and asks her husband to drive her to the doctor.

She puts on a large overcoat so as to cover the stuck seat, and
they go. When they get to the doctor's, the man lifts his wife's
coat to show their predicament. The man asks,

"Doctor, have you ever seen anything like this before?"

"Well, yes," the doctor replies, "but never framed."
