What's a Ten?: Getting one of your team mates to guess the song you're humming for Humdinger (the yellow card sa Cranium) first.
What's Not a Ten?: Realizing you've been humming the wrong song.
(unnecessary explanation: the song at the card was Stand By Me but I hummed Lean on Me; Rinah got it right, in fairness to my lowly humming skills, but still, the point went to the group with the guy who knew how to read)
