Face

I congratulated a colleague on a job well done and they replied;

'I'm not just a pretty face you know'

No. You're a pretty fucking ugly face you know.

Chips

Exclaiming how inexpensive something was, someone said to me;

'They are as cheap as chips'

Like you're wife.

Eggs

Stating that some thing is a definite someone might say;

'As sure as eggs is eggs'

As sure as eggs is eggs, you're a gonner
