Sing it in your lingo. Imitating some other dialect or patois or regionalism always sounds ludicrous (I agree with Mr. Happy) unless you are very familiar with it.

The "th" is difficult for many from other than English-schooled backgrounds.

Thaler, the coin is an example. Pronounced Taler in German, as are all words beginning with TH. Some other languages are similar.
They easily becomes Dey, and Those becomes dose.

And do you say "thuh" or "thee" or "de" or "duh", in "--- dictionary is on the shelf."
