when I'm playing on my mac and someone tells me to do that I always say I tried doesn't work
But when you're on Windows you fall for it.
Once I pretended to be a noob and asked a really dumb question. Someone told me alt-f4, so I disconnected and connected again a few seconds lated and said 'u tiked meh!!!!1111,' and they actually believed I did it.
I did pwn him by saying "Say /sad IDLow 10 times"
This made my day.
