But there was an old song my pappy used to like to sing:

Chickie in the car, that car won't go. Chick car* go.

With the Chick pronounced like Chicken.

*No, I have never heard it pronounced with an R by a native.

Now that I think about it too long, I can't swear that I haven't heard Tschicago. Or Tsch'caw go with precious little vowel sound between the Tsch and the c.

Where Tsch represents the initial consonant cluster in Chicken.
