I think that was possibly the funniest episode i have seen, the way they were ramming eachother, fat stig...  the bit where they were sabotaging james may's air con had me in stitches.  Oh and "Turning right on a red light...  the only thing that America has given western society" 

If any americans take offence to having a bit of fun poked at them, i wouldnt watch that episode.
New Orleans was a bit of a shock, never hear about what is happening there anymore.
