Old, but cute story:
So I was at the mall with my son and nephew years ago when they were young. At the time my son was a little chunky, ya know he liked his Cheetos. My nephew on the other hand was too skinny. As we walked around the mall, someone made a comment and asked if my nephew was my son. I was like, thanks! Just cuz he and I are super skinny, you think he’s my kid.
