US comedy shows

I enjoy all the US comedy shows, but I do wish they were so not predictable with the targets of their jokes.

Two years after he has left office, and I’d say David Letterman is doing 20 times as many references to George W Bush as to Obama.

And Sarah Palin gets targeted more than I’d say anyone else.

Now don’t get me wrong – I enjoy the jokes at their expense. Humour is humour.

But where are the Obama and Biden jokes?It’s not like there is a shortage of material – esp with Biden.
