Never, EVER Flush These Things Down a Toilet

Correction: This video says "drinking water" at 2:47, but should say "harbor water."

Turn out, it's not just about clogging the john. Those pipes lead to the sewers, where wet wipes, condoms, and grease from your kitchen sink can congeal and turn into huge masses called "fatbergs.
