pass out drunk and naked.
Either get drunk or shoplift.
Stay sober and have the time of your life!
Pretend to be really happy about a lame gift
Buy a present for themselves
demand to see Santa to complain about last years gift?
Fart and belch
waste money on a tree
Complain about the socks and tee shirts they got for Christmas?
run away screaming till there sanity comes back
