Bryan Cranston Hilariously Fails At 'Word Sneak' On 'The Tonight Show'

It's a "Tonight Show" game called "Word Sneak," and the rules are pretty simple: Take five random words and casually sneak them into a conversation.

On Monday night, host Jimmy Fallon took on Bryan Cranston, who stars in the new "Godzilla" film out next week.

Turns out Cranston's pretty good at "Word Sneak," but there was one word the "Breaking Bad" star had some trouble with -- and the results were priceless.

Watch the video above to find out what it is... then see if you can sneak it into the next conversation you have.
