Monday

I made broccoli in my new steamer last night. I bought a big bunch of fresh broccoli and as I prepared it I sang the broccoli song, and for the first time in my life the words fit.

And my lady she went downtown
she bought some broccoli
she brought it ho-home
She's choppin brocco-lee
she's choppin brocco-lee
she choppin brocco-lay
choppin' brocco-lay-hay...

I always sing the song when I'm around broccoli, even if it's frozen or just a picture on a can of soup in the store. This has been happening ever since like 1984 when I saw Dana Carvey perform his ode to broccoli on TV. And the reason I have the link to it is because I had to look it up for Eli. He had no idea that I got the song from TV and all these years he thought it was just another one of the stupid songs I make up for everything I do. Like broccoli just routinely turns me into a singing kitchen ass. I don't know why he would think that. I never sing to cauliflower. Or peas.

Choppin' Broccoli is like Conjunction Junction and Beans & Rice. It sits dormant in a tiny little autistic segment of my brain and waits. And as soon as I'm provided with the correct stimulus like fresh broccoli or a picture of broccoli in the grocery store or someone just mentioning the word broccoli around me, it's out. Almost unconsciously. Like reflex.
