I don’t know why, but I just realized that “spork” is a really funny word. I know, its a mixture of “spoon” and “fork”, but still…its just damn fun to say. Spork.
Another one is “snuffalufagus” (the thing from Sesame Street). I always loved saying that too.
I bet you guys can come up with more…
I’ve always thought the word “falafel” was fun to say.
Plus (and I think this may just be me) the words “impala” and “Malibu.”
I especially like Malibu. Mal-i-booooooo.
I always thought the word “particularly” sounded really funny.
Mirriam-Websters’ online dictionary just got audio, so if you go to http://www.m-w.com you can hear your funny words pronounced by one of two people who had to say all the words in the English dictionary into a microphone. Call me easily amused, but I had fun with it. 
Also call me immature, cause my favourite one is “boobies.” 
Thesaurus, since my son went through his dinosaur stage, the word just tickles me. When someone takes it and doesn’t put it back in it’s assigned spot, I say, “Where is Thesaurus Rex?” It used to dissolve him into giggles (and it is a heavy beast) but alas (also a funny word) now the kid just rolls his eyes. Someday he will post that it to a thread titled, Silly or Stupid things your parents say.
Well, my favourite word is also convienently(sp?) fun to say: FLINGE!
(don’t be suprised if it’s not in the dictionary, me and my friend made it up (it means to attach a flange onto something.))
Y’know what word I’ve always found really funny?
“Both.”
It doesn’t look that odd, but say it a bunch of times and you’ll see what I mean. God I hate that word.
Road. Rooooood. Rowud.
Yes. Mr. killdare discovered this feature while I was on the phone with my mother. I could hear a strange voice saying “Motherf$#ker” over and over and over, while he howled with laughter.
m-w.com has two sounds for “son of a bitch.” One normal, and the second one is “sumbitch.” Hehe.
“elope”
“cantaloupe”
“pungent”
“unguent”
“salve”
…and for edwino and Rasa…
“omatidia”
I have one word.
drapes
I know I’ve mentioned it before, but God, that word kills me and I don’t know why. Ever tried to go shopping for curtains when you giggle like a schoolgirl every time you say “drapes”? (Heehee.) It’s awful.
Wankle Rotary Engine . . .
Especially when spoken with a British accent.

Crunchy: If you like Malibu so much, have you tried caribou? Sing it like Frank Black from The Pixies. Caribooo-ooo-ooo!
Personally, I’ve always liked sputnik. Sputnik, sputnik, sputnik. I want a wire-haired terrier named Sputnik.
I think this may very well be my most deranged post to date.
I think futon is a funny word. Not only that, but I think it sounds like a bad word too.
“Futon me? Nooooo, futon you!”
Tansania. Fun to say.
Squash. Funny sounding.
“Pamplemousse”. French for grapefruit.
“Desodorisant”. Missing the accent over the first e. Sorry. That is also french, and means deodorant.

My first double-post. Don’t I feel like a fool.
I’ve been found of heteroscedasticity (an important concept in inferential statistics) since hearing it. It’s a big long word, that I can never spell correctly unless I look it up (I always want to spell it …osked… instead of using the letter “c”), but for all of that rolls off the tongue surprisingly easily.
Unfortunately, this one doesn’t make the online Webster’s.
Smock!
Smock Smock Smock Smock Smock
Don’t knock my smock or I’ll clean your clock!
