Well, this was one way to keep Harry Potter fans interested as they grew up. Modeled after Harry's first broom, Mattel's now discontinued battery-operated Nimbus 2000 featured a grooved stick and handle for kids who wanted to ride it around the house. The dubious part: it vibrated. Some of the (now deleted) comments on Amazon were so good, they had to be written with a wink: "I'm 32 and enjoy riding the broom as much as my 12 yr old and 7 year old," wrote one satisfied customer. We bet.
