I'm sure there is a special column running in PrivateEye to celebrate the insanity that is the royal wedding. Here's my contrbutions.

There website says "We have had a high level of interest", can't think why
Also One of my favorite islands, Niue, has had some stamps printed.
They do make a loverly couple, and if this goes the same way as the other royal weddings, you can simply tear down the dotted line.
