Calvin:   I've got an idea, Dad

Calvin:  Maybe I'd get better grades if you offered me $1 for every "D"; $5 for every "C", $10 for
              every "B", and $50 for  every "A"!

Dad:    I'm not going to bribe you Calvin.  You should apply yourself for your own good.

Calvin:  Rats.  I thought I could make an easy 4 bucks.
