Ricky Gervais is upset with pandas because they're not doing all they can to stave off extinction.
 
The animal-loving comedian admits he's happy to do everything in his power to raise awareness about the world's endangered species, but he thinks pandas could be doing more to help themselves.
 
Appearing on "The Daily Show with Jon Stewart" on Tuesday, Gervais joked, "We're all rushing around going, 'Let's save the panda, let's save the panda' - but they're not meeting us halfway. They're not having sex.
 
"When did they stop having sex? When did they (become) middle-class bohemians going, 'We're not gonna have children.' It's ridiculous.
 
"The Chinese... they're so worried about the panda they've started giving their pandas in captivity Viagra. That's absolutely true.
 
"I looked into this and the normal copulation of a panda is two minutes... but on Viagra they can copulate for 30 minutes - but what difference does that make? You either finish or you don't, so what difference does it make how long you do it unless Viagra makes you ejaculate for the full 30 minutes until they just slip off the back of the female... who's left there like a big wobbly s**nk bomb."
