There was two good times:
1. Me and my friends were really bored so we called a random number, this is how it went:
Friend: 'Hi, this is Sally from the 'Adult Sexytime online store', I'm just confirming your order for the 'Big Girl blow up doll', 'Men, Men, Men Magazine' and your assortment of anal probes, is this correct sir?
Random Guy: 'Uhhh no, I think you've got the wrong number'
Friend: 'Well what's your name sir?'
Random Guy: 'Umm Andrew Hayes'
Friend: 'Yes thats the name we've got here'
Random Guy: '\Wait, is this Miranda? Yeah i know its you, c'mon I'll tell dad i caught you f***king Ricky.'
It turned out a million times better than we expected, imagine the awkward conversation he had with his sister later on...
2. Me and my friend called a random number and we got an answering machine so we left a message saying ' Hi it's Jamie, call me back' , left it silent for a few seconds and then started making sex noises really loudly and then stopped and then said 'Wait stop, i think i left the phone on'
