Ricky Gervais previews 'Life's Too Short' in new Tweet That video
Gervais and Merchant's highly-anticipated new BBC Two/HBO sitcom, which centres on the life of dwarf actor Davis, launches next month.
In the comedy trio's latest video, Gervais makes Merchant carry Davis aloft, while the Willow star flaps his arms like the famous bird from social networking site Twitter.
Gervais also reveals details of a Steve Carell cameo in the series, which he describes as "one of the most excruciating scenes we've ever done".
