Alley Cats

 Some British feral cats wander around making observations and being cats. Not much in the way of a narrative, but still manages to be very entertaining. It's from the mind of Ricky Gervais and it's only 6, 15 minute episodes, that really aren't much more than clever banter, yet Alley Cats still manages to be screamingly funny. From a cost benefit perspective, its hard to top the amount of laughs you will get over the time you have to spend to get them. Go for it.
