Delicious chocolate with peanuts inside.

The most appropriate use of a blue peanut M&M is to throw it at John Wilson during parties. Never eat a blue peanut M&M, for they contain an unknown substance that may kill you.
"Don't eat the blue peanut M&Ms!"

"I will never eat another blue peanut M&M..."
