I wanna be chopping broccoli!

I've been watching my broccoli plant since April! It still has yet to produce one crown of broccoli. Everytime I go out to the garden to check on it, I always have this Dana Carvey song in my head. Do you know that song? He did this skit on Saturday Nigh Live, and it's so funny. However, 5 months later and still no "chopping broccoli" for me. What's going on Broccoli plant? Why are you not growing any crowns?
I found part of the "chopping broccoli" song on YouTube in case you've never heard it.
