Well, a banana is a fruit. It is yellow, and edible. Obviously. They rule and can be used to get out of situations.
John- What did you do that for?
You- BANANAS! *runs off*
'Hey Harriet, would you like a banana? They taste lovely!'
An extremely enticing kind of cake. It is wonderful in everyway, it's fun to shout out at a loud volume, because it pisses people off. It also involves cheese.
'Wow, dude, this cheescake tastes lovely!'
'CHEESECAKE!'
