As far as 'SNL' sketches go, there's only ever a precious few that make it into legendary status.

There is, of course, the 'Dear Sister' sketch with Bill Hader and Andy Samberg, there's 'Point / Counterpoint' with Dan Aykroyd and Jane Curtin, and then there's the 'More Cowbell' sketch with Christopher Walken, Will Ferrell and Chris Parnell.

The sketch, for those that don't know, follows the recording session for Blue Oyster Cult's 1976 radio hit, 'Don't Fear The Reaper' and its cowbell track. Of course, what made the sketch more funny than anything was Will Ferrell's impassioned cowbelling and Christopher Walken's deadpan delivery.

Here's the original sketch, just for posterity and the fact that it's a great sketch.

So, sure enough, when Will Ferrell was on last night's 'The Tonight Show Starring Jimmy Fallon', it came up as both Ferrell and Fallon were in the sketch and Ferrell is on hosting duties for 'SNL' this weekend. Interestingly enough, Ferrell brought up an interesting point about Walken that he didn't realise until years later - namely, that people talk to him about that sketch more than any of his other work.

'The Deer Hunter', 'True Romance', 'Pulp Fiction' - nope, it's all about legendary record producer Bruce Dickinson. You're gonna want that cowbell.

Take a look.
