Fireman Sam

Recently the boys are into a show called, "Fireman Sam".  Show name sums it up, a fireman named, Sam being the hero by doing his basic fireman duties.  Today they decided they were becoming Fireman Caleb, Fireman Kallen and Fireman Ian.  I put up hidden fires around the house and they had to put them out.  Basically there was a lot of laughing, and hearing nonstop screaming of the word, "fire" or siren sounds.
