We love a great viral video.

First up, at the OIympics were the dancing videos.

Tom Daley mugging sexily on a beach, or the US Swim Team chirpily lip syncing to Carly Rae Jepsen's Call Me Maybe. Watch for an especially enthusastic performance by teenage swimmer and gold medallist Missy Franklin.

Then, came the world's "happiest Olympic worker" as Rachel Onasanwo entertained visitors to the London Olympics.

But, as always, there is Lego.

And we think this is quite possibly the best Lego sports video ever, thanks to the Guardian.
