The Giraffe Joke

At this point, I was teaching a girl of 7.  Her 5-yr-old sister was always in the lesson as well (very well-behaved).  Neither girl was particularly tall - the younger one was about as tall as my navel.  At the end of this lesson, the little one gave me a hug (fairly standard procedure), and, still with her arms wrapped around me, looked up.

Girl: Miss Anna, do you know why giraffes have such long necks?
Me [smiling at the irony]: No... why do giraffes have such long necks?
Girl [starting to giggle]: Because... because they have smelly feet!!!

Siblings - Almost

A 5-yr-old, in one of her first lessons, had her fingers all squished up on her bow.  In an effort to give them a bit of breathing room, I asked:

Me: Do you have any brothers or sisters?
Girl [with a look of 'surely you know this']: Well... yes... but they're still in mummy's tummy.

I should point out that her mother was about 8 months pregnant with twin boys at the time.
