Via Ananova:

A group of deaf people turned up to watch a rock band who were promoting their new album called Songs For The Deaf.
Posters and leaflets had been distributed to advertise Queens Of The Stone Age's show at Spiders club in Hull.
A club spokesman says the party of 37 people expected a special event for the deaf.
The Sun says they left after finding out they'd turned up to watch the band who played Glastonbury in June.
A band spokesman said: "We can see the funny side now but it was a bit baffling at the time. The group never thought their album would cause such confusion."
A club spokesman says bouncers got confused when the party started using sign language.
But they realised the mix up when the group said they were there for the Songs For The Deaf night and threatened to call trading standards if they didn't get in.
He said: "They were angry and said they had phoned us to check we were holding a Songs For The Deaf night. They didn't see the funny side at all and left straight away."
