I need to invest in ninja throwing stars

I need to invest in throwing stars so when jerks on the street yell out "Excuse me miss, you dropped something," because they think they're funny I can bend over, pull a throwing star out of my ankle holster, and then chuck it at them.

Yes, these are the kinds of plans I come up with to combat catcallers.

UPDATE: It happened again today (day after initial post was written)! "I think you dropped something, miss. You dropped your halo!" What in the flying fuck is up with this? A viral marketing campaign by Beyonce? I need to get to www.ninjathrowingstar.com, STAT!
