Alan Partridge: Alpha Papa (2013)

Alan, the selfish, wormy git finds himself in the thick of it when an ex-employee at the North Norfolk radio station gets a gun and goes a bit mad.
Most comedies tend to lose momentum after about 50-60 minutes when the gags peter out, but Alpha Papa keeps them on target for about 90% of the running time. The social awkwardness provides chuckles, but the real treasure is the razor-sharp wordplay. It's the smartest, funniest thing I've seen in a very long time. If I'd had a full bladder, I'd have pissed myself.
