The universal excuse for obtaining something you shouldn't have. Occasionally used for something illegal. Can be substituted for "My dad asked for me to get it for him."
Sometimes chain stores don't buy this excuse.
Store Clerk: Why do you need to buy this potassiam nitrate?
Bob: Uhhh.. school project.
Store Clerk2: Why do you need this spraypaint?
Bob: Uhhh.. school project.
Store Clerk3: Why do you need a lighter?
Bob: My dad asked me to get it for him.
