A man goes into a restaurant, sits down and starts reading the menu. The menu says:
Broiled Botanist $5.95 per plate
Fried Ornithologist $7.95 per plate
Toasted Ecologist $7.95 per plate
Grilled Wildlife Biologist $69.95 per plate
The man calls a waiter over and asks "Hey, why does the Grilled Wildlife Biologist cost so much more?"
The waiter says, " Are you kidding? Do you know how hard it is to clean one of them?!?!"
