What are some fun and free things to do on a birthday?

I want to celebrate a friend's birthday and we both don't have much money. We live too far from each other so we are meeting into the city. Do you have any suggestions as to what we can do for free or cheaply in the city?

WHAT CITY???

ummm, for me/ I don't know
free concerts, sneak into a movie, weed? lol

Do you like to skate? I don't know if it's cheap or if you have a rink there. You could just hang out and go to the Mall or is that old?
OK, everyone, take it from here

Oh! Oh! Do you have a Krispy Kreme Donuts there? I think you can get a box for around $5. Pig out!

lol

Hang out with friends
walk in the park
pic-nics
family &/or friend games
arcade

Wait till its night time and stroll through the streets

City life is way more fun at night

And all the lights

"oh my god'

beautiful isnt it
