okay, step one, you need to be fast or at least have a lot of stamina or running energy
number two, go to one of the small ice cream trucks, buy one ice cream
Step three, when they are grabbing your cone from the freezer point the opposite direction and say to wait for your friend.
Only do next step if she looks away
Step four, grab your hand into the truck and fuckin run.
Don't take too much or take money because they will call the cops.
If you tried this or will, make a post about your experience, i'll read it.
