Always fun having The Block NZ's Ling and Zing in studio!

Watch them play The Block Clock, where they have 60 seconds to honestly answer questions about themselves, and their Block neighbours.

But when it was time to find out what their last argument was about, Zing pulled a fast one on his brother.....and Ling wasn't too happy about it!

Watch above.
