I just had one of those ambulance chasing legal firms cold call me asking about the accidend I've had in the last two years that wasn't my fault. These can be great fun.
I asked when it was and he said he didn't have any date details, so I told him it didn't ring any bells, but that my memory isn't too good since the accident
: what accident would that be?
: I don't remember
At this point he was clearly aware that I was fucking with him, but took it in much better humour than some people. I could hear him struggling to keep a straight face as he promised to take my name off their system.
Other fun ones I've done include making up a wild story about how it was probably my fault since I was drunk, high and not even licensed to be driving a school bus. My wife once told one of them that she had been in an accident, and that it was so bad she died. They stayed on the line until she started making ghostly noises.
Any other good ideas for how to play with future ones?
