spudometer
A handy-dandy gauge dat tallies up how many potatoes you've harvested, prepared, eaten, etc.
If da Little Red Hen had been baking potatoes instead of bread, her non-helpful colleague-animals would have glanced at their individual spudometer-readouts and found dat they all displayed da exact same humiliating/disappointing tally-figures:
"Number of spuds planted: 0
Number of spuds tended: 0
Number of spuds harvested: 0
Number of spuds prepared: 0
Number of spuds baked: 0"
And lastly, of course {{{drum roll}}} ---
"Number of baked spuds given me to eat: 0"
"Number of spuds planted: 0
Number of spuds tended: 0
Number of spuds harvested: 0
Number of spuds prepared: 0
Number of spuds baked: 0"
And lastly, of course {{{drum roll}}} ---
"Number of baked spuds given me to eat: 0"
