Top Gear: Christmas Special
This was by far the best Top Gear episode...
I haven't seen PT2 yet but now I know part of what happens Grr.Spoiler alert....in title
Sowwie It's just as funny even when knowing it
I actually found it funnier when they set the stig as a target in the previous episode. I just wonder when it'll blow over, I think the stig punished himself hard enough when he decided to leave the successful trio.
