You're the Bee's Knees!
The Australian Native Teddy Bee, like many other bees, use 'combs' of stiff hairs on their legs to brush the pollen from their fur onto their back legs. Many bees have little cupped areas on their back legs where they store pollen while collecting more pollen. The second photograph is a bee in my backyard, collecting pollen from a borage flower to add to its "pollen pants". So bees are awesome, and their knees are very cool, being part of their funky pollen pants.
