Bad joke

[twelveboar]

Knicked this off another forum, but I don't see why I shouldn't inflict it on here:
A chap goes to the zoo, but when he gets there there's only one dog........















....It was a ****zu!!!!

My wife laughed out loud when I shared that joke with her!

It took my wife 10mins to get it - it was a sort of delayed reaction. And then she complained that the joke was rubbish... but her favourite TV comedy ever is 'Allo 'Allo!!!
