Grilled Geologist

A man goes into a restaruant, sits down and starts reading the menu. The menu
says:
Broiled Accountant $5.95 per plate
Fried Engineer $7.95 per plate
Toasted Teacher $7.95 per plate
Grilled Geologist $25.95 per plate

The man calls a waiter over and asks “Hey, why does the Grilled Geologist cost
so much more?”

The waiter says, ” Are you kidding? Do you know how hard it is
to clean one of them?!?!”
