To cap off an eventful day that also saw an album release, a Good Morning America appearance and a whole lot of tour controversy, Britney Spears swung by the Jimmy Kimmel Live! studios for a couple skits and a reprise of 2/3 of her set from that morning's GMA performance. Though Britney's live showing was just as disappointingly lifeless as her other performances of late, her involvement in the night's comedy was impressively competent—including a surprisingly game bit involving her mixing it up with the Jackass crew.

The evening began with Jimmy checking on Britney in her dressing room, comparing "tattoos" they had agreed to get of each other before the show. (Britney's was much smaller and done only in pen ink—doggone it.) Later, when Johnny Knoxville was talking with Jimmy on the set, he alluded to a cut scene from Jackass 3-D featuring Ms. Spears, which was then shown in its full, likely fabricated glory. The scene featured Britney semi-unwillingly agreeing to be flung bungee-style in a used Port-a-Potty, covering the pop star in human waste (although luckily for those with weak stomachs, the visuals are kept vague with the gross details) and inspiring her to attack some of the cast members in an excrement-soaked fury.

Spears then went on to perform hit singles "Till the World Ends" and "Hold it Against Me" in her typical low-energy haze, but even if her appearance did little to dissuade notions of her having fallen off as a live performer, her earlier comedy showing was competent enough to prove that there's at least a speck of humanity left behind those hazel eyes. Here's hoping that's what it proves, anyway, and not that her on-retainer pharmacologist is good enough at his job to forcibly inject a pulse into her for ten minutes at a time.
