I believe that when a pre-recorded telemarketer calls for the second time in one morning, asking you to 'please hold' as soon as you answer the phone, it is a totally appropriate response to say "Cunt!" and hang the phone up.
...I really hope it was a telemarketer.
Who the fuck else would ask me to hold as soon as I picked up the phone, though? I can't imaging them expecting a sane person to comply.
