Cheat Feet Socks
Woodpecker Laboratories is kind of like a cool, former-hippie uncle that gives great advice and provides invaluable tools for maneuvering oneself through life. First they came out with this friendly reminder decal that affixes to the toilet seat (fecal matter, you stay where you belong!) and now they follow up the bathroom companion with an equally helpful accessory for math class.
Cheat Feet socks feature the 12 x 12 multiplication tables split between your right foot and left foot. Now the simple act of sitting ankle to ankle will gain you instant access to tricky times combos, such as 6 x 4 and 12 x 9 and the hardest simple multiplication act of all, 8 x 7.
