Baby Stroller Thief
You know those moms who do their morning runs with their babies in those rolling strollers?
1) If I stole a baby, that's the first thing I'd put them in. I could run away from the scene of the crime and it wouldn't look suspicious.
2) Do you remember how annoying it was to rollerblade on the sidewalk when you were a kid? Your blades sinking into the sidewalk cracks every few feet? Do those cracks give babies little tiny headaches?
