Drawing on your stepchildren is fun.

The night before we went camping Chaos-man crept into the boys' room and carefully, amid fits of shaking silent laughter, me standing in the doorway, fists shoved into my mouth, drew large curly mustaches and goatee beards on each of his children with my eyeliner.

In the morning Bigmad woke up first, and appeared in our doorway sleepy and stretching, mustache still proudly sitting above his top lip. Keeping straight faces and trying not to meet each others eyes, we answered his questions about camping and our trip away. SmallMad woke up soon after and came bounding into our bedroom, stopping short when he saw his brother. "YOU'VE GOT A MUSTACHE!" he cried, pointing at his brother, who looked at him incredulously in return. "WHAT? SO HAVE YOU!" They both scrambled for the mirror and examined their faces with horror as we cracked up with helpless laughter.

"DAAAAAAAAAAAAAD! YOU DRAWED ON US!". They were even more horrified when they found out it was girls make-up we used, and they've been plotting revenge ever since. I've told them we sleep with our eyes open, but I'm half-expecting a counterattack and have hidden all the permanent markers and highlighter pens just in case.
