Funny Words, Not Ugly

One word that I dont necessarily think is ugly, but funny is "bubbles." What could be funnier than the word "bubbles"? You can say it so many times that it doesnt sound like a real word! Bubbles bubbles bubbles bubbles bubbles bubbles bubbles. Actually, any word that has a similar set-up, like giggle or wiggle or jiggle! They all sound funny to me, I dont know why...
