Portal 2 Sounds | A Portal 2 Soundboard containing all in-game quotes and dialog.
I think I may have found the greatest site on the Web. Yes, of course it’s a Portal soundboard. It lets you choose between Portal 1, Portal 1 Music, Portal 2, Portal 2 DLC, and Portal 2 PTI (as well as TF2 and TF2 Music). It also lets you search quote text and search by the speaker. It’s really easy to find your favorite quotes, which is good because I didn’t know how often I wanted to listen to Portal quotes until I found this site!
