True story

 Instead of sexual fantasies I have athletic fantasies, like someone will steal a purse in a crowded square and I'll run after them, hitting them with a can of thrown peas while they are running a diagonal route. And I'll point to someone to call 911 while I'm chasing after the second guy. Or something subtle will tip me off that the apocalypse is coming and I'll sprint non-stop the 30 blocks to save my daughter from her daycare right in the nick of time. And then I'll have to chase down a car on foot to keep them from getting away and starting the apocalypse.
