So I was playing Counter-Strike the other day, and I decided to create a server. I waited for someone, and one finally joined, but they did nothing for about 5 minutes, my ammo suddenly got removed, and my knife and Deagle disappeared, too. Then they started chasing me while saying over and over "Sneakers O' Toole, please let me eat your poopy ice cream. I will give you an iPod." over and over while the sound of what I think is a Vortigaunt from Half-Life 2 singing. Stranger still is that they had a Greg Heffely playermodel. I didn't have any mods, mind you. and then I got cornered and I couldn't move away from him. I could jump, but that's all I could do, and then they killed me. What could this be?
