Old lady at Prince of Wales Hospital So today I was walking through the Prince of Wales Hospital looking for where my appointment was and an old lady who must have been at least in her 80s walks past me and says ""hey I've got a joke for you, why don't lobsters share?"" I look at her all confused and ask why and she replies ""because they're shellfish."" I'm sure this jokes been heard before (I know I've heard it just forgot) but it was more the randomness of the situation that made it funny.
