Where's my diet plan?

Making plans to dine
Love to eat out, except I
Have to make the call
Make sure my guts don't revolt

Need to find the list
Of the things I can ingest
Am I allowed pears?
Can I eat steak that's there?

Can I have some veal?
Are veggies my only meal?
Not stuck in my mind
Been a little lax, alright

Kind of a problem
Don't want my guts to hurt
Crimp on the ev'ning
When I have to go hurl

Can I have some beer?
My diet plan's lost, I fear
That my stupid brain
Will recall the wrong things, lame

And that's a problem
I could end up dead
Not what I wanted
That'd make a real mess

Tearing up my desk
Tryna find that stupid list
Hear a "Ding!", now I feel bad
Diet plan was a text
