Bodily functiuons are inherently funny.
 

They crack me up, yo.

Shit, I spelled functions dodgy...

Which body functions do you mean, Duck? Why do you put yo after your posts?

The same reason Vyvian starts everything off with "Good Goth!"

And bodily functions such as pooping, taking a wee wee, sex, farting. Mainly anything to with your ass and some other stuff.

The funniest is when the tiniest little girls make the most epic burps. Cracks me up.

I knew this little girl years ago who could rip the most Pumbaa farts this side of the Serengeti. It was awesome.

Thats quite interesting. I have seen many little girls that are good burpers as well, it is undeniebly funny.

I can burp the abc's.

It's the yo's that make Duckman cool.

Yo!

Argh, see, I just can't do it like he can...

There used to be this awful website that would allow you to generate fart sounds of varying qualities. You might've liked that...

We've started selling these godawful lollipops in my work which have two buttons on the handle. One makes a rather unconvincing burp noise, the other a soggy fart. The amount of time I've spent trying to keep seven year old boys from playing with them... *grumble grumble*

However, I agree. The word 'Poo' alone makes me giggle like the nutter I am.

... hehehe... poo...

The word poo is hilarious.

i find it funny that my wife can burp louder than me(shes only 4"9)

Cool, your wife's real small, yo!

LOL. If anyone makes a fart noise or farts, it cracks me up. I tried to play this game where we had to see who would last the longest without cracking up while someone tries to make us laugh. Someone caught on that I laugh at that, so I'm always out first. LOL.

You know Kenny from Kenny Vs. Spenny? I have that sense of humour...
