Sound Effects Make Everything Better

My youngest son Finn HATES having his face wiped off. This is a major bummer considering the fact that he is almost always a bit of a disaster. He somehow gets peas and blueberries in his eyes, up his nose, behind his ears... Everytime I wipe him down he fusses and cries and tries to bat me away. Today I made a ridiculously lame shooting sound while I wiped him. Not only did he sit still but he laughed through the dreaded wipe down! What is it with boys and their sound effects?
