Zoey and Lukas think it would be fun to be twins, so in this episode they're seeing double! They explore "twin" words - homonyms and homophones - and have some punny fun.  Two sets of twins compete in the game show where teammates have to describe and guess some sound-alike words shown in pictures. Twin stand-up comedians Peter and Tom Hartman stop in and play a game of irreversible word pairs. Just like fish and chips and soap and water, these twins' names are also irreversible. It's always Peter and Tom, never Tom and Peter! The challenge has two sets of twins run a three-legged race to find objects that are always referred to as pairs, like scissors and pants.  Lukas programs Booboo Bot to finish some puns, but when Booboo Bot confuses a sound-alike word, he becomes an overheated mess.
