So King Henry, I wonder, do we look like ants from up there? Do you need an oxygen mask and are your legs built earthquake-proof?
Also how does the start of a space shuttle look from above? Do you sometimes take a star and give it to a girl? Are you friends with the man on the moon?
Ok, seriously, I guess most people only make these silly jokes because they're jealous or just for smalltalk. I consider myself average though I note a lot of smaller people ask me to get something for them that they can't reach, at work for example, let's just say you can make fun of everyone in some way and I find it easier with small people actually than with tall ones(as the lame questions I made up above should indicate).
I wouldn't worry too much about it.
