The best way to get kids giggling uncontrollably is to get on the subject of nipples. My nephew was maybe 10 yrs old and I took him and his sister out for hamburgers, even the kids at the tables around us were cracking up...I just kept on with a straight face...what's so funny about nipples? You go to the hardware store to buy nipples...the cat has nipples...the pcv valve on the car has nipples...YOU have nipples...
