Veep Dick Cheney's skill with a shotgun has spawned some jokes.
1. My favourite one liner so far is the one that hold that it's still safer to go hunting with Dick Cheney than it is to drive with Ted Kennedy. Yeah, I know that one has been around in a dozen versions since the incident hit the news. google "cheney hunting kennedy driving" and see what turns up.
2. For a more sophisticated approach, check nottawa's clever line on Bush and quail/Quayle.
3. The top of all, though, is The Daily Show.
