twice on Sunday

[Mike Hussey]

Sam speaks to Kaffee:

Sam: And if I were Dawson and Downey and I had a choice between you or your father to represent me in this case, I'd take you any day of the week and twice on Sunday.

What does "twice on Sunday" mean?

I think what he means is that this person is so good, he'd want to work with him every day and, since Sunday is a day off and people have more time, he'd use this day to work with this person even twice.

The expression is any day of the week and twice on Sunday. The sentence means "I would absolutely, definitely pick you rather than your father."

 

[Charlie Bernstein]

It's a common expression. It's an emphatic way of saying "Always!"
