The dogs bollocks.

[ladycornyofsilke]

Do I need to add an apostrophe as in:
The dog's bollocks.
Or is that just a bit daft when you're being all sweary?

If you are a true pedant, then yes you do!

But won't that spoil the moment?

It depends just how good the thing is you are describing, I think. If it was the dogs' bollocks, it would be really amazing, surely?

Oh yes, I see it now.
