Are you old enough to remember the polio-era line: "funny as an iron lung"? After all, what kind of person would find funny the notion of someone fighting to breathe?

The clip closes with video of Cheney fighting to get a breath of air.
Cut to Mika, doubled-over, laughing hysterically, literally to the point of tears.
