Excalibur Electronics Motorized Pool Lounger
Rule your pool from a suitable throne--the inflatable Excalibur Motorized Pool Lounger
(US$150), which Time Magazine named one of the Best Inventions of 2006
. The joysticks on each armrest control independent propellers to transport your monarchical self in any desired direction.
For more-competitive water fun, check out the same company's Motorized Bumper Boat
(US$60). Buy two and encourage your paladins to engage in noodle jousts for your royal favor.
