Self Stirring Mug: No Spoon Required (Link)

This is a very cool mug to have if you are so busy to waste few valuable seconds stirring your coffee with a spoon!

this mug has a miniature battery-operated propeller at the bottom of the well that spins at 3,000 rpms at the touch of a button on the handle, automatically stirring your beverage and eliminating the need to dispose of stirrers or find a place to leave coffee-dampened spoons. At your command the propeller re-stirs mugs of hot chocolate, coffee, or tea, preventing chocolate or sugar from settling out of solution, and overcoming the traditional challenge of adequately mixing honey in a hot drink.

The mug includes a lid to keep contents from spilling and to retain heat, and the lid can be placed underneath the mugs base as an impromptu coaster. The mug is lightweight injection-molded plastic sheathed in a stainless steel exterior. Requires two AA batteries.

This mug is available at $30 for two mugs at Hammacher Schlemmer. The mug also requires 2 x AA batteries.

I also found another similar mug from Initial Ideas that is sold for $23 and requires 2 x AAA battries.
