Thought I'd share this in the hope it saves someone else a little trauma!
OH slipped on a pair of clean undies the other day, only to experience some unexpected movement down there.
Slipped them off again (rather fast I might add) only to find a big black spider inside them - must have come in with the laundry when I brought it in off the line!! Luckily it didn't bite him or he could have had some awkward swelling to explain too!
Moral of this (true) story? Always shake your clothes before putting them on!
