The Three Little Pigs went to lunch one day. Pig #1 ordered a bountiful lunch. Pig #2 ordered a healthier but still substantial lunch. Pig #3 ordered water.
As the meal went on, Pigs 1 and 2 ordered refills, seconds and desert; pig 3 kept requesting more water.
Finally, pigs 1 and 2 asked their friend, “What’s this with all the water? Aren’t you going to eat ANYTHING?”
Pig 3 smiled pleasantly and responded, “One of us has to go wee wee wee all the way home.”
