3 little piggies walk in to a bar.

waitress comes up and asks the piggies what they'd like to eat

first 1 says, i'll have a steak

second one says, me too, i'll have a steak

third one says, i'll just have some water

so the waitress brings back the food, and later asks the piggies if they want dessert

yes, said piggy 1, i'll have chocolate cake

i'll have fruit salad, said piggy number 2

i'll just have water, said piggy 3

so the waitress turns to piggy 3 and says, why have you been ordering water all evening when your friends have been ordering food?

piggy 3 says, well someone has to we we we all the way home
