lol at "researchers who spy on people in public restrooms"

Same here, Makalu.

who raised these people?!?!

LMAO spying on public restrooms? At any rate, I make it a habit to wash my hands after the restroom. This reminds me of a Seinfeld episode. Can anyone tell me which one I'm thinking about?

Poppy's Restaurant....taste the pizza, Jerry!

bogus.

Complete B.S.! There's no way two-thirds of men wash their hands after using a public restroom. The actual number is probably about much lower. Observer effect?

Naughty, filthy 'researchers' .. in 'public' restrooms!
How many times did 'they' wash up their dirty 'hands'?
