During the Block competition where the boys were giving away some cash to callers, they gave Deborah a yell who came through with something a little unexpected for Mike and Jay.
She said she's a massive fan of The Block NZ and started singing the theme song in hopes that Mike and Dunc would hand her the $400.
The only problem was, she seemed to have not heard of the theme song ever and have randomly sung 'na-naa-naa-naaaa-na-na-naa-na.'....then went on to blame her 'flu'.
At least she got all the words to the song, the boys gave it to her anyway.
On ya Debs.
