Baby baffled by his weird new set of wheels

Things that look hilarious riding around on a Roomba: cats in shark costumes. Things that don't look hilarious riding around on a Roomba: five-month-old humans.

At least, that seems to be the opinion of this baby, who looks a little confused by the set of wheels that have been rigged up for him using a robot vacuum cleaner and a Bumbo chair.

Meanwhile, the father of the "Roomba cowboy" thinks it's the funniest thing ever.

The video was uploaded to YouTube in 2010 but is now enjoying another spin in the internet spotlight.
