For the second night in a row on 'The Colbert Report' (Weeknights, 11:30PM ET on Comedy Central), House of Windsor expert Hugo Vickers gave Stephen Colbert a lesson in royal etiquette. This time, it involved teaching Colbert how to act and what to say in a meeting with The Queen of England.

But, since they didn't have the real queen to practice on, Colbert brought out a blow-up doll dressed up as Queen Elizabeth II for the exercise.

"I find this quite difficult, you know," Vickers said, upon seeing the dolled-up sex toy.

"I do too, I've never met the queen before," Colbert responded.

"If, at any point, during the ceremony, she deflates, is it allowable for a commoner to re-inflate the queen?" Colbert asked Vickers.

"No, I think this is wrong. As an Englishman I find this very uncomfortable."

If that made Vicker's stiff upper lip quiver, he should have heard what Colbert's new Comedy Central stablemate Norm McDonald recently had to say about the Queen.
