Jar jokes

A man is out west driving and on the edge of town comes across a tourist stand and sitting in front is an Indian chief right out of central casting. Dour look, full headdress, a glass jar and a sign that says "Indian chief know all! $5". So the fellow's curiosity gets the better of him and he goes up to the chief, puts $5 in the jar and asks "What did I have for breakfast on this day 10 years ago?" Chief taps his chin for a moment and says "Hmmm eggs. You had eggs!"

"Eggs?" shouts the guy "Everybody has eggs! I've been had!" throws his hands in the air and leaves in a huff.

Ten years on, as fate would have it the fellow has occasion to be driving through the same town and sure enough he comes across the same stand, Indian chief, sign, and jar. So he stops the car and saunters across the road, goes up to the chief like a smart-ass, holds up his hand and says "How". Chief taps his chin for a moment and says "Poached."
