I think many of the classics still remain the best. I loved reading about the BBC spaghetti tree episode. This morning I got a call from my son asking why I had gone to work on Saturday, and maybe it is the withdrawal from Spring Break, but it actually had me thinking I had missed a couple of days. There was also the 1857 invitation to watch the "Bathing of the Lions" at the London tower.
I looked up a bunch of the "youtube" variety but most of them were lacking in originality or creativity.
