In all seriousness...

I gave my kid a bath last night in chin deep water and bubbles to his chin. Apparently the bubbles were a 'tend beard like knights have. Knights have 'tend beards, especially when they joust. To complete the ensemble, Harry wore a red plastic IKEA colander on his head, complete with handle. It was his helmet. This colander is probably our most used "toy". It was less than $5, and probably only $1 but I don't remember. He used bubble wands as jousting sticks to collect rings like they do at the Renaissance Festival. The tub was his horse.
