Top Gear, Series 15

Richard:
[After describing the problems in his Land Rover] Mind you, compared to Jeremy's design flaw...

[The camera cuts to the front of Jeremy's car, which is swaying from side to side rather violently due to the height of Jeremy's "flats"]

Jeremy:
[trying desperately to control his Citroen] Ahh! Ahh! AHHH! Oh my God! No, this is terrifying! I can't begin to describe what this feels like. Oookay, wallowing quite badly. [narrating] I asked James to pull in behind to assess the gravity of the situation... but he wasn't much help. [the camera cuts to inside James' car, where James is roaring with laughter.] And to be honest, nor was Hammond. [the camera cuts to inside Richard's car, where he is also in complete hysterics.]

Jeremy:
I've cocked up, I know I've cocked up. Wahaaa, low bridge!

Richard:
[over the walkie-talkie after Jeremy cleared the bridge] Jeremy, did you make a note of how tall it actually is?

Jeremy:
[to himself, muttering] No, I didn't. [over the walkie-talkie] Yes!

Richard:
He hasn't got a clue.
