That's a good old TG vid there, and I think more similar to what 5th Gear are showing now.
I agree with everyone else, i do think TG has been on a decline, what with everything being so scripted and simply not funny anymore. As Andy Wilman said in his blog on the TG website, the trio are now acting up their "cartoon" sides too much, and frankly it comes across to me as being desperate. If you've noticed, the best TG films tended to be the genuine ones, those where it's just the 3 of them having a good time. Films like Bonneville, the North Pole, Africa, America etc etc. Those are great because it's the 3 of them behaving completely naturally, reacting to various situations as they see fit, on the spot, instead of some preposterous slapstick act. It's their spontaneity that makes the show gold, and they (the entire TG team) have rather lost the plot of late.
