Practical Jokes

We're moving office soon so I've been spending time configuring some new phones. Somewhere along the line, one of the guys in the office here switched my phone out and froze the interface - to the point I thought something had gone wrong and was looking up how to factory reset the phone

Before we go - i'd like to repay the favour

Any ideas as to something subtly funny that isn't a-hole behaviour?

Best one I've seen but involves getting access to their mobile phone is the old "switcheroo of the contact number".

Insert your number into a contact of theirs and away you go on sms.

Used to be much easier before complicated phone locks.

We stitched a mate up at the pub beautifully one arvo... he told us about a one night stand a couple of weeks prior then left his phone on the table. We did the honourable thing, changed up her number to a mates who was sitting at the table, then slowly but surely over the course of 5 pints proceeded to inform our buddy she (really he) was pregnant and keeping the baby !!
He went from hero to zero in no time
