You cheating armadillo

The story:

I was utterly distracted by my incredibly important job as a Beardy
Policeman in the Vancouver Transit Police and didn't realise I was
singing Blondie under my breath as I harassed random foreigners.
When I reached this line in the song the mad Irish woman I was
harassing at the time halted me, only to point out that I had in fact
been singing the song incorrectly. As you can imagine I was
mortified and promptly let her go.
