I've heard of bats in the belfry, but this is a new one.

From the Telegraph:

Teenager finds baby bat in her bra

Abbie Hawkins, a hotel receptionist, thought her mobile phone was ringing when she felt vibrations coming from her clothes.

But she later discovered the tiny creature tucked away in the padded pocket of her underwear.

As staff and colleagues crowded around, Miss Hawkins, 19, produced the frightened bat, which was the size of her hand.

"I keep thinking how could I have not known it was there?" Miss Hawkins said. "I will certainly be checking my bras every morning from now on."

Jaime Eastham, of the Bat Conservation Trust, said they had never heard of a bat being found in a bra before.

But she said the animals roost anywhere that appears dark and safe.

Dark and safe indeed.
