The Carbonaro Effect - Season 1 Episode 3 -

Posing as a thrift store employee, Michael makes shoppers believe that a real waddling duck is just a lifelike decoy and confuses clerks with a never-ending chain of hangers. Then, he convinces liquor store customers that some corks are made of cheese and a wine can freeze on command. Plus, in a museum he shocks a gullible new employee by destroying a priceless piece then impossibly reconstructing it.
