Another from Sesame Street - not sure why the whole thing is still in my brain

It is I, Captain Vegetable, with my carrot and my celery
Eating crunchy vegetables is good for me
And they're good for you so eat them too
For teeth so strong your whole life long
Eat celery and carrots by the bunch
Hooray for me Captain Vegetable, crunch, crunch, crunch

My kids loved that song, although continued to despise vegetables
