Biden has shown a willingness to adopt things that werent his own before. He is to be dismissed like all the other permanent guests on Sunday morning. The talk shows are as far as hairplugs will ever get..
I'm not certain Biden has had any original thoughts. It's likely the whole "making love to his wife while his children slept" creepout comment was stolen. After it was hilariously pointed out his children were grown, the story died away (thankfully).
