3956 - One Saturday joke revisited

OK, I posted this joke on Saturday.

Old Macdonald...
...spelled "redirection" without any consonants.
(think about it)

I thought I would get some comments on it, but no. No one except John commented at all!

So did every one get this joke? I had to figure it out. Was I just slow? Was it that easy? Or did everyone just blow by it with a 'meh'?

I'll put the answer in the comments if I remember after midnight.
