My daughter goes to a Catholic school. Her school superiors are mostly nuns.
One of these days I am going to get a pink slip from the school principal to let me explain where my daughter gets her nursery rhyme lyrics.
Here's an example (intellectual property by my very creative husband). My daughter was singing this at the top of her lungs when she got home from school. I quickly locked my door because I was in a call with somebody from work.
Please sing this to the tune of "Five Little Monkeys"
One little Monkey Jumping on the Bed
One got shoot right through the head (BAM!)
Momma called the doctor and the doctor said,
Clean those monkey brains off the bed!
Sing it with me (real lyrics please. It is still catchy)!
