How about we make some plans to smoke while planning out our great get away?
But for starters, think of a weekend that you suspect you both are free. Think of the plans you can make him have one day, I'll figure out plans to make him have Sunday. He just doesn't have to know that both plans are totally fake and we're throwing him into the back of a van to take him north.
Oh... maybe we can get him drunk and stoned that Friday so he'd be more willing to come with us. It wouldn't be kidnapping that way, right?
