Buy an organ, never know when you might need one.

tempting, but I have money saved in case of emergency

You could probably get a decently cheap rocking horse for $160. Nothing too good of course, but you get what you pay for.

rocking horse.....rocking horse.....please explain why I would want that

How about you just act like a JACKASS and get a fishing rod, stick your highest bill on it, somehow hid the fishing rod in your shirt, make sure there are a couple of people around, sneakily "drop" the bill, let the line get alittle bit long, and when someone tries to pick it up just take a few steps and wait until they reach for it again and take a couple few more steps. After you've had enough fun (how could you?) Walk up to it and pick it up and show the person(s) that tried to pick it up the fising line

haha i have done that b4! epic

Another idea is to convert it to all single bills (160 $1 bills) and just go around smacking people with it.

(yes, I'm very disrespectful to people when money is involved, don't blame me, look at my name )

I suggest you buy some headphones if you are into music.180 usd can get you a decent pair of some monster turbines, pending controltalk. but besides for consumer electronics, I suggest you you keep the money for various occasions, such as dates or any social outings.

It pretty much provides the experience of riding a real horse, all while riding back and forth.

I hate horses lol. and I have headphones. epic senheisers
