Is David Letterman jealous of Sarah Palin and her multi tasking abilities?  After all, while she has a loving spouse, five children and one grandchild, can skin a moose, catch fish and has governed both a small town and a state while electrifying citizens of flyover country who treasure both their guns and religion, he has managed to father only one child at an age when others are grandfathers and their careers, like his, are in decline.

Perhaps that's why he  inadvertently complimented   her Tuesday night.   

Letterman joked that in the future, she hopes to be the next "octo-mom."
