Throwing knives. They aren't loud when thrown, they can kill with one hit (Given the person using them is good), and I could wear leather gloves so there won't be finger prints. (Maybe I thought about this one a tad bit much).
What's a great way for a uke to flirt? My friends want to take me out to an 'LGBT event' but I don't know how to introduce myself or what to talk about! >3<
