Mnemonic device for NOUN and VERB?

I work with special education students who have a very difficult time remembering the difference between a noun and a verb. I thought if I could come up with a simple mnemonic device using the letters in the words that would help them NEVER forget the definition of each word, my work life would be complete. While I am working on it, I wonder if there are any clever people who could help come up with some great mnemonics for these words to help these worthy kids. THANKS IN ADVANCE!!!
