I really like this posting / video from Tony Heller.

The Australian temperature record is generated largely from short term, fragmented station temperature records – with no data prior to 60 years ago. This video shows the data from all 1,657 NOAA GHCN stations in Australia.
He then proceeds to show all of the stations to the beat of “Teenage Wasteland”. I’m particularly fond of this as I tend to be a “visual thinker”. I just “soak up” things like the short fragment lengths with very few long records, the widely divergent ranges (how can average things when one is a 10 C range and the other 2 C?) and the tendency to concentration is just a few years in or near the “baseline period”. I can just see the data and know it’s crap.
Then, the music makes it fun ;-)
5 minutes and 10 seconds:
This second one is a bit less fun, but still useful:
The US has by far the best temperature data set in the world. Most of the stations in the US Historical Climatology Network have long term coherent data, This is what the raw temperature data looks like- before NOAA starts tampering with it.
