Well, it's not the dumbest thing, but the first dumb thing that came to mind...
My brother had taken the boat and came back with a large haul of shrimp, so the family was gathered together to "de-head" the shrimp for freezing. As we sat there, plucking shrimp heads from shrimp bodies, My brother paused and looked at the two piles and remarked,
"At this rate, we'll end up with more heads than shrimp!"
I could only look at him and grin in reply:
"THINK about that, will ya?"
And just for the record, not one of us that night came across a two-headed shrimp!
