Just a funny story - but one year, my dad really wanted a keyboard and mouse set. My mom told him he was NOT allowed to buy it (we had a working keyboard and mouse), so he snuck out one day after work and bought it!
On Christmas Eve, he strung up his own stocking and put the keyboard and mouse in it - and told my mom "OH LOOK, WHAT SANTA BROUGHT ME THIS YEAR IS JUST WHAT I ALWAYS WANTED." and she couldn't say anything in front of us, kids.
It took me years to figure out what my dad did - but he still thinks he was SO clever.
