sounds like....
As I was sitting on the couch I read a joke online about a guy saying to a blonde "if you say green beans really slow it sounds like gullible" and she said it. Curious to see if this actually worked I looked up above my laptop sreen to my beautiful blonde girlfriend and said "Hmmm, it says that if you say green beans really slow it sounds like gullible." Sure enough, my girlfriend stares in the air and starts lipping "green...beans....gu-lli-ble....green...................beans....NO IT DOESN'T!!" and starts laughing because she finally got it.
Try it out and see if it works for you
