Thanks @prodigalist for the hint!
The file is in the Counter Strike : Source/hl2/hl2_sound_misc_000.vpk
Then, opening it up with GCFScape, you go:
Don't abuse emoticons like that again.
Alright! Sorry for that.
I believe its a sound file from HL2, try looking through the hl2 vpk files.
Or maybe Counter strike Source, since I don't have HL2.
Thanks for the enlighten!
Don't abuse me or my emoticons like that ever again.
You just gave me an idea! (not abusing emotes)
