Ricky Gervais celebrated his return to Twitter by posting a photo of some on-set antics from his upcoming TV series 'Life's Too Short.'

In the photo, Gervais and guest star Johnny Depp are seen pushing star Warwick Davis ('Harry Potter') into a toilet, which the British funnyman said was to protect the diminutive star from mice. If we had a nickel for every time we've used that excuse...

In January of 2010 Ricky Gervais rage-quit Twitter, slamming the mico blogging service as being "pointless" and "undignified", among other criticisms. Because Gervais is nothing if not dignified.

Now it looks like the acerbic funny man is prepared to eat those words, 140 characters at time.

As long as he keeps posting ridiculous images like the one below, we'll keep following his Tweets.
