Pilgrims are born at Costco

Phillip came home from pre-school the other day, mentioning that his buddy Dennis was born at COSTCO (large warehouse retailer). Upon further questioning, he also mentioned that Dennis had told him, that he had walked thru every state, and that he is a pilgrim. Apparently, there was also a sex change involved - because Dennis said: "first I was a boy, then I became a girl, but now I am a boy again." We had no further questions.
