It was the bell of the Sharpening Truck! Quickly, Mr. Widdle grabbed his pocket knife from his drawer and bolted down the steps to the street. The truck was already pulling away, so Mr. Widdle had to run up the block where he found it parked and ringing its bell on the corner of Cabrini and 190th st. He handed over his pocket knife to the man inside who proceeded to expertly and inexpensively sharpen the blade on the loud grinder inside the truck.
As the pocket knife was being sharpened, Mr. Widdle thought back to the last time he used the truck, years ago in Brooklyn, He had heard stories about the truck, and when he finally heard its bell ringing, he raced outside so as not to miss it. The man in the truck looked at Mr. Widdle and exclaimed, "What, are you in your underpants?!!" Mr. Widdle was indeed only wearing his boxer shorts, as he was in such a rush he forgot to put his pants on.
Back on Cabrini, after handing over a few dollars and thanking the man in the truck, Mr. Widdle walked home thinking he might use his new sharpened pocket knife on some theater flooring repairs he'd been neglecting. When he told his wife about the Sharpening Truck, she asked, "Why didn't you tell me? I could have given you our kitchen knives!"
