I’ve always been partial to “snickersnee,” myself.
doody! booger!
Kukamunga! WallaWalla! Seattle!
Grace, this is hilarious! I rarely want to swear, but I think I am making Futon my personal swear word.

Zebra: Calvin and Hobbes, right? 
Father: Gorn!
Mother: What’s Gorn, dear?
Father: Nothing, nothing, I just like the word. It gives me confidence. Gorn…gorn. It’s got a sort of woody quality about it. Gorn. Gorn. Much better than “newspaper” or “litterbin.”
Daughter: Frightful words.
Mother: Perfectly dreadful.
Father: Ugh! Newspaper…litterbin…dreadful tinny sort of words. Tin, tin, tin.
Daughter bursts into tears
Mother: Oh, dear, don’t say “tin” to Rebecca, you know how it upsets her.
Father (to Daughter): Sorry old horse.
Mother: Sausage!
Zebra, I was just thinking of that! Hobbes also likes to say “quark”.
I like to say:
Frond
Crinkle cut
Pie
Wow
Supercede
Miller, what the hell was that?
tomorrow
cupboard
motherboard
Of course! It’s my desire to see futon accepted as an alternate curse word. 
Snorkle:
And I don’t see any way to get audio on my MW online. Where do I go?
My personal fave, from when I was about 8, is Lake Titicaca. It was quite a riot in class when we found it in an atlas. 24 years later, it still cracks me up.
Lozenge is my funny word. I say it ‘Lah-zennnnn-ge’.
Oh, you have a sore throat? Would you like a lozenge?
Lozenge lozenge lozenge… Hee, I’m laughing right now.

I’ve always loved “hemoglobin” or, as the british would spell it “hæmoglobin”. Say it fast , or stretch it out.It’s just a fun word to say!
BAMBOO BAMBOO BAMBOO!

I’ve always been partial to:
Fart
“For Accelerating Rude Toxins”
Edited. Sounds like “Ed Ed Ed Ed”.
Pope.
Potato.
Cube.
Quark.
Fruit.

Mmmmmm… caribooo

I’d also like to formally add aardvark and 75% of words that originated in Australia. Diggeredoo springs to mind.
Some of my favorites:
Napkin
(Brings to mind imagery of little gnome-like creatures. The Keebler Napkins, perhaps?)
Pillow
(Sounds like what it is, I guess. A big fat thing you can hit people with).
Diphthong
(Even funnier when pronounced “Dipthong”).
More to come if I think of any.

Vacuum

You can tell the quality of the artist by the quality of his SMOCK!
