Re: Rotated screens and "pranks"
Back in the Windows 3.1 days I pranked a colleague by swapping the function of the left and right mouse buttons and setting the vertical sensitiivity to max and horizontal to min, so it looked like you could only move the cursor up and down.
Arrived next day at the office to find the BOFH running malware scans on it. Ho ho ho.
Not long after, the same machine, along with most of the others in the office, had its memory nicked by "RAM Raiders" (for a time, the value density of DRAM was greater than gold). The thieves had, very courteously boxed the PCs back up again after removing the DIMMs so the reason why none of them would boot up wasn't immediately obvious. Guess where the finger of blame was pointed?
