What's a clever comeback for this?

I wad talking tinny friend, Mason, about my weight. He was talking about how weak my bf was because he thinks I'm heavy. Hen mason asked how much a weigh, I told him "102" which is true. Buy if you want to get technical, 102.4 ANYWAY! When I told him how much I weighed, he said "102? How do you stay upright in wind?!". What could I say back that's clever? :)
