blister sister

Someone who shows up when the real work is done then acts like they took part.

Dilbert and the intern spent days proofing the manual then Wally pulled a blister sister and ran a final spell check to claim all the work.

Blistered Sister

A nun with a prominent and questionable cold sore.

Father Mulveaney couldn't help but notice the blistered sister sitting in the front row at mass. He made an appointment with his family doctor after service just to be safe.
