When does it happen?

For every person who celebrates Christmas, there is a point at which you say to yourself, "Now, it's Christmas." It's that point when that holiday spirit moves you.

For me, it occurs when I hear the BC Clark holiday sale jingle.

Interestingly enough, I found out a couple of years ago that it is the same for Megan Mullally. She actually sang the jingle on The Tonight Show.

So, what's your trigger?
