When I was a little brat, I would go up to people and say.....okay, say this really fast 2 times...
One fine fellow, he felt smart
Two fine fellows, they felt smart
Three fine fellows, they all felt smart
Well, inevitably, whoever would do it for me would fall for it, and end up with a tongue twister. I remember I did it to a dear old great grandmother. I told her, Grams, say this....and repeated the saying.
She looked at me for a moment and said......Fart.
Ruined all my fun.
