Another toilet invention I've been thinking about lately is a toilet meter that rates your dumps on a scale of 1-10. Sometimes going to the bathroom is hard work and I think it'd be nice to be rewarded for some of your best performances. The best part is about it is that if your dump scores a 5-7 the toilet dispenses a delicious cup of French roast coffee and if you manage an 8-10 the toilet rewards you with several Arby's coupons.
