Loved that one! Brings memories of school textbooks flooding back, like drawing little beards on the sperms on page 78 of my biology books, or best of all my best mate's prized "Tiger book of sport, 1976" which he's liberally defaced with flatulations, phalluses, flared trousers and large afro haircuts on every page.
He's 32 next week and he's still got it!
