Will Ferrell is so excited about the royal wedding that he appeared on last night’s “Late Show With David Letterman” in his morning suit, gushing about “the pageantry” of the pending nuptials between Prince William and Kate Middleton.

Or, as he calls them, “Kate and Willie.”

He also had a special greeting for the royal couple. Warning: It gets a little sloppy and Letterman has to break out the Windex.
