Testo Pet Foot

My pet foot is my left foot,
I keep it close to me,
closer than a beekeeper keeps his bees.
I kick it with my right foot when it steps out of line.
My right foot is a lemon but my pet foot's a lime.

I could tell you about my pet foot, it tends to make me leave my shoes and socks rolled up and stashed behind your couch.
I could tell you more but I do believe I've got my pet foot stuck in my mouth.
