Duck Quacks Don't Echo

Seth presents a theory that is commonly debated: Is it really possible for bacteria from a flushing toilet to reach a toothbrush sitting on a bathroom counter 6 feet away? Our experiment puts the urban legend to rest once and for all (hint: the results are disturbing). Later, Tom challenges Seth and Michael to test a theory that is easier said than done: Will any of them be able to achieve the seemingly simple charge of eating six saltine crackers in a minute or less without a sip of water?

Things get heavy as a two-and-a-half-ton truck makes an appearance in-studio as four ceramic coffee mugs attempt to support its entire weight. Tom's challenge of writing the number six while rotating your corresponding leg clockwise baffles everyone.

What happens if you give someone a virgin drink but tell them it's alcoholic? Seth tests the theory of whether drunkenness is truly in the eye of the beer-holder. Michael tests a shrimp's endurance, believing it's greater than the average human.

Seth puts the nickname "bird brain" to the test, believing that pigeons can remember human faces. We all know there's nothing like a little fun in the sun--but is your swimsuit making you...dumber? Can pudding dance--and can you dance on top of pudding?

Is it the color red that really makes a bull angry? Can you hang upside down from the ceiling fan using only glue? Can a yolk be separated from the white of an egg using only an empty plastic bottle? Hosts, Tom, Michael and Seth solve the puzzles!

Tom, Michael, and Seth prove that: You can stretch a bathing cap enough for an adult to fit inside of it. There are mites that live on your eyelashes that are visible under electron microscope. People are more likely to believe statements that rhyme.
