Can anybody answer this?

Why in the hell are those narrow baloons so hard to inflate? The balloons I speak of are those balloons that clowns or other people use to make things with, you know what I mean?

Last Sunday, when I was at my sisters, nobody could blow them up! A few were blown up by my brother in law before the party, but the ones we (me, my dad, my brothers, my mom) tried to inflate during the party were impossible. I wish I had a camera, because people (yes me) produce funny faces when trying to blow those skinny baloons up.

And yes, we were stretching them beforehand.
