Ma Vache est Jolie

I've been listening to this song lately called "J'ai pas vingt ans" and have been trying to sing along with what lyrics I can understand. This morning as I was singing along loudly in my car I realized that something was wrong:

Moi, je sais la tache.
J'ai maquille ma vache.
Moi, j'ai le temps.

which loosely translates into:

I know the task.
I put makeup on my cow.
I have the time.

Somehow I don't think that's what was intended, but it's forever etched in my brain.

Vive la vache!!!
