My ass

She'll use my money to buy a new car, my ass!

You're his brother, my ass! You look nothing alike.

And then I found out. "Single" he told me? Single, my ass! Not only was he married, oh, no, he had six wives!

My boss screwed up again, and of course it's my ass that has to deal with it.

Now I gotta drag my ass to work. He says it's fine, but get real—you know it'd be *my* ass on the hook, if anything happened.
