Your Opinion?

My cousin (11 years old and male) wanted to see if he could set a record. He wants to see if he could set the record of having your feet tickled for the longest time. I told him he can't, because of the fact that someone who is not ticklish could say they are and last forever having their feet tickled. He refuses to admit he is wrong, but I do give it to him, he has really ticklish feet and can last a while. I can't even touch his socked feet without him giggling. He had his sister tickle his feet (with him wrapped in a blanket with his socked feet sticking out of one end) for 5 minutes and 32 seconds and he was in complete hysterics, his eyes were watering. I just want to know if the public can tell me how long their kids, cousins, or brothers can last having their feet tickled and how ticklish they are. Just to see where my cousin is at (Even though I still think its a pointless record) I WILL GIVE 10PTS TO ANSWER WITH GOOD OPINION AND PERSONAL EXPERIENCE WITH TICKLING KIDS
