Just to prove that these sorts of things don't happen just to me: earlier, my brother was trying to calling the office of the grad school program he got accepted into.
brother: "Hi, this is..."
grad office machine: "I'm sorry, but our offices aren't open on Friday."
brother: "What?"
machine: "Please call back during the week!" *hangs up*
brother: "WHAT?!"
me: "Isn't it...Wednesday?"
Brother: "WHAT THE HELL JUST HAPPENED."
