We're from the government, Ma'am. We know what we're doing.

This is too funny.

JEFFERSON CITY, Mo. (AP) -- A law taking effect this week could make criminals out of those who bring Tupperware onto many Missouri rivers.

The law was intended to reduce the floating debris from abandoned foam coolers in the state's waterways. But lawmakers, apparently a little rusty with chemistry, barred the wrong plastic.

The white foam coolers commonly called "Styrofoam" are made from expanded polystyrene. But the law bars polypropylene. That's a plastic found in things like dishwasher-safe plastic containers but not usually used to ferry drinks down a river.

The mix up means river floaters can use foam coolers without fear. But someone caught with a dishwasher-safe plastic container could risk up to a year in jail.

Sometimes our rulers require no snarky comments on my part.
