Wii-jected -- HSN Host Smashes Tennis Demo

Posted Oct 20th 2009 8:00AM by TMZ Staff

Here's a grand slam moment -- some HSN host was hocking the Wii video game system the other day, when he wound up, took a swing ... and accidentally fired the controller right at the flat screen TV!

"...and there goes the tennis racket ... I didn't have it on there all the way."

Oops.
