Roomba trail
When your newly purchased, exquisitely autonomous technology discovers a big fat pile of dog shit during its 3am 'time to clean' wake-up programming and proceeds to generously distribute the filth in a robotically inspired carpet dance throughout your entire household.
Guess what? I just followed a dog shit roomba trail covering every room in my house...when did that fucker learn to climb stairs!!? We're done with the robot thing...hell no to that!!
