Here is the logic behind the dry British sarcasm...
Jeremy calls the 370Z a "hen".
What type of person would want a car that looks like a hen?

Bill Oddie is a bird watcher.
Therefore, if you drive a 370Z people will think you are like Bill Oddie.
Come on. There has to be someone else on this forum that finds this funny...
Anyone...
