Poppin' Fresh, more widely known as the Pillsbury Doughboy, is an advertising mascot for the Pillsbury Company, appearing in many of their commercials. Many commercials from 1965 until 2005 (together with some for GEICO between 2009 and 2017) ended with a human finger poking the Doughboy's belly. The Doughboy responds by giggling when his belly is poked (Hoo-Hoo!, or earlier on, a slight giggle "tee hee"). - Source: Wikipedia
