Bear couples are just like every other couple in that, after shaving each other's beards into identical chinstraps, they like to relax in front of the TV and enjoy a pleasant session of mutual masturbation.
Wait, that doesn't make any sense. After all, no two chinstraps are completely identical. Still, we think we're right about the whole mutual masturbation thing. Just look at these guys! They look like they've done this a million times and would be perfectly content to do it a million more times.
