Last month, John Oliver tried to save the last surviving Blockbuster in Anchorage, Alaska by donating rare Russell Crowe memorabilia such as the leather jockstrap that the actor wore in 'Cinderella Man.' And the gesture wasn't lost on Crowe, who has honored Oliver by making him the namesake of a chlamydia ward for koalas at the Australia Zoo Wildlife Hospital.

Chlamydia poses a massive problem to the world's koala population, which is already vulnerable to extinction because of the loss of their habitat to land development in Australia. The chlamydia infection rate among some groups of koalas is 100 percent, because infected mothers pass the disease on to their joeys. So the hospital ward is a prank that could actually save this species from extinction.

Crowe hinted at the stunt in April in a tweet commending Oliver's generosity and love for Crowe's homeland.

Which was news to Oliver, who feels nothing but disgust and disdain for Australia.

"I've never shown love for Australians or Australia," Oliver said yesterday on 'Last Week Tonight.' "At most, I've shown morbid curiosity for it the way a 9-year-old pokes a dead frog with a stick. I'm endlessly fascinated and grossed out at the same time."

But that didn't stop him from enjoying Crowe's decision to name the chlamydia ward after him - and to hang a plaque in bearing his name in the hospital, which was unveiled recently by the family of the late Steve Irwin. In fact, Oliver was so overjoyed that he tore down the set of 'Last Week Tonight,' saying that he'd achieved everything that he'd set out to do on the program.
