Name your best pc prank.
I'll get this started :
on my mates parents pc i edited their host file :
C:\WINDOWS\system32\drivers\etc\hosts
which acts like a local DNS server
I entered :
www.google.ie - 192.168.1.1 ( this IP is fake for this purpose )
When his parents came back to the pc everytime they opened up google it re-directed them to a brazilian porno site.
Mate was mortified for ages coz his parents thought and probably still do think that he was looking up brazilian scat porn on their pc.
