A story from the famous Susan Malmsten

Heather and Todd were excited about the arrival of a new addition to their
small but soon-to-be-large family.  Having just been accepted to med school,
Dr. Todd pulled out his freshly bought stethoscope and told Heather he had
an idea.

"Let's listen to your belly!" Todd exclaimed.

"Yeah, whatever dear..." Heather said, while sitting there trying to
remember where she was (yes folks, pregnant women often go crazy)

Todd excitedly put the stethoscope to Heather's belly... and listened
intently.

"Hey I hear something!" Todd said

"Are we at the zoo?" Heather asked quietly to no one in particular.

From within the depths of Heather's large round stomach came this voice...

"Hey hey hey!  How is everyone feeling tonight?!!  Spleen, you look great! 
Colon, glad you could make it but please take a shower next time, P-U!!  Hey
Liver, have you lost weight?  You look fab!"

Todd was a little confused... what could possibly be going on?

Heather was definitely confused.  "I think I left my pants in the grocery
store" she mumbled.

Todd continued listening....

"Well for those of you who don't know me (and who wouldn't, I'm the biggest
thing in the Belly these days) my name is Hodd and I am here to make you
laugh! (clap clap clap)"

Heather stared at the man listening to her belly with a stethoscope... he
looked kinda cute.  She wondered who he was.  Then he started chuckling. 
Strange.  Her belly began rumbling... and she was starting to feel gassy. 
The weird doctor man was laughing pretty hard now.

"This kid is hilarious!" Todd exlaimed inbetween laughter and fell to the
floor about to wet his pants.

Heather tilted her head to one side inquisitively.

She pulled herself up off the couch with great difficulty, and joined Todd
on the floor.

Tears were pouring out of Todd's eyes and he continued to roll around on his
back laughing.

Heather began to rock side to side.  "Oh, I get it.  We're boats, aren't
we!"

Row row row your boat, gently down the stream
Merrily merrily merrily merrily
Life is but a dream.

... ah yes, life is but a dream.

and with that I bid you adieu.
