A 50-dollar bill in Canada is called a McKenzie because of the guy on it, William Lyon Mackenzie King. He was a prime minister, but nobody cares about that.
'I just got paid, and I'm gonna blow all my McKenzie's on pizza.'
'That's just one McKenzie. I need ten of those to survive this month.'
'He was a prime minister? I'm not even a prime minister of my own brain.'
