Guess who is coming for dinner?

Robert Loretta and his wife Roslyn had just sat down to dinner of a nice barbecued teryaki chicken when the knock came at the front door.

'Guess who's coming to dinner?' Mrs Loretta joked as she got up to answer the door.

The hammering grew louder, so luckily she looked out of the peep-hole, as she often does, before opening up - and saw a 6ft alligator scrambling up the wall as though it was trying to ring the bell. link
