Betty White guest stars once again on Bones. "The Radioactive Panthers in the Party" is the tenth episode of the show's 12th season.

Brennan goes for a drive and enjoys herself while undercover at the Demolition Derby on Bones.

No matter how it turns out, we know that having Buck and Wanda back is going to be entertaining. Having Booth and Brennan do some smashing and crashing as their alter ego's will be nothing but fun, and if that's not enough, they'll probably catch a killer too.

So who do you think is going to be driving in the demolition derby? We're sure that Booth will want to take control but Brennan's definitely going to want to drive something other than her Prius. Perhaps they'll both be out there driving on the dirt.

Yes, Wanda's got that awesome curly, frizzy, 1980s big hair look, but there's just something about Buck's mullet that makes us unable to look away...even though we might want to.<P><P> When not even someone as handsome as Booth can salvage a hairstyle, you know it's time to retire it.

We'd say our favorite undercover duo has returned in the nick of time. After the drama of having someone trying to kill her children and then suffering through her father's murder, Brennan could sure use something to make her smile. <P><P> It appears that getting behind the wheel at the demolition derby may be just what the doctor ordered.
