On my last day at work, I took an empty Marlboro carton to use as a box for my 14-year-old sister's Christmas gift as a joke. It's been sitting in the trunk of my car for a while. The other day, my dad needed to borrow some coolant, so I went and opened it up, not thinking anything of it, and then there's a carton of cigarettes just hanging out, begging for an explanation. Luckily he knows I'd never smoke, so he probably would have been cool with it even if I didn't say anything. But still, now he doesn't get to be surprised by it come Christmas...
