Okay, let's think about this for a second. This is important doings a transpirin' here.
If Santa says...
"Ha! Ha! Ha!" - he's crazy, needs to be checked into a nuthouse.
"Hee! Hee! Hee!" - Santa's drunk or high on something.
"Tee hee! Tee hee! Tee hee!" - isn't right either. It may play in West Hollywood but not anywhere else... maybe SF or at Larry Craig's house.
"Har! Har! Har!" - Santa's now a cheesy stand up comedian.
"Haw! Haw! Haw!" - Santa's got hay in his teeth with a pig under one of his arms.
"Guffaw!" - That's right out. You can't say it three times and sound convincing.
"Heh! Heh! Heh!" - That just sounds smug and condescending.
And if they just have Santa laughing through his nose, that's just wrong wrong wrong.
"Ho! Ho! Ho!" it is and always should be. It tells the kid, 'Hey I'm a big friendly guy who has your best interests in mind and will help you fulfil all of your materialistic needs in one hedonistic day of unwrapping big retail provided parental love.'
