Ahhh, yesss... The ol' "Dump-a-load". Had to use those on the dairy farm, for "Pasture-patty" removal. (A.K.A. "Barn-burgers", "Meadow-muffins", "Alley-apples", "Cow-pies", etc..) Could never understand why the bin on those thing just HAD to be in front of the drivers seat. Our's also had a hook on back of the seat, where you hung the gas-mask. Whenever somone was leaving, to go do the "doody duty", they said they were "gonna go take a dump".
