It took me exactly 4 weeks (slow I know, I am out of practise, but still) to mack my collegue, the one controlling the company jukebox and therefor controlling what music we get to hear here, as follows:

I get him a cup of English tea, with milk.
He plays me Christmas is all Around by Billy Mack.

Very Macky indeed.
