Yeah but you gotta admit, it prolly just slipped out. People have grown up with santa saying "ho ho ho". It would take a while to reprogram the brain to think of santa going "ha ha ha".
The rule *is* ridiculous.I hate when people don't realize that they're getting behind and/or enforcing idiotic rules. (aka - the people who thought up this whole thing) ... *sigh* Poor santa. Now he's saying "boo hoo hoo". :/
