Time waster

I have just discovered what is possibly the world's greatest ever time waster. I suppose in the interests of the truth, the whole truth and nothing but the truth I should amend that statement, or at the very least, elaborate on it. I have known about its existence for a fairly long time, but today I visited the site for the first time. I'm referring to YouTube. I am amazed at the wealth of videos there are to watch - and the variation in the standards of filming. I suppose I have spent a couple of hours just flicking through - channel hopping, as it were. I did come across one which has possibly the most remarkable display of precision drumming I have ever seen. The film wobbles about a lot, especially at the beginning, but fast forward to the fine minute mark (or a little before) and the drummers of the Royal Marines show just why so many people reckon they are the best in the world.
