The best of something, something that is excellent. Originally coined as a sarcastic rejoinder to bee's knees
"How are you?"

"Oh, I'm the bee's knees. The elephant's instep, if you would."

"Jolly good!"

"Right-oh, let us giggle uncontrollably while eating these buttered crumpets!"

"Ah HA ha-ha-ha-ha-HA!"
