The Lick O Meter. But why, dear Mama, why?

‘How many licks does it take to get to the center of a Tootsie Roll Tootsie Pop? Well this clever keychain contraption counts every one! Tootsie Pop or any other lolly fits inside the keychain counter and licks are tallied on the LCD read out. Comes complete with one Tootsie Pop and batteries are included.’
