oh dear.
you make this assumption from 2 episodes
Any two episodes from the first two series are funnier than the two shown so far, and 2 episodes is a third of the series. I've not laughed out loud that much in the two episodes shown but I was laughing out loud every 30 seconds in the first 2 series. The first 2 series were arguably the greatest in British television, but the third one: the novelty has worn off and the jokes are a bit samey. :\
I love The Inbetweeners, but the third series has really disappointed me thus far.
