They are more of uncalled insults than anything comical..
Not all are bad, but to be honest..many of them are beyond my tolerance...
The ones you mentioned were very disappointing. The Kachra one should be added to the list, it was a totally uncalled and disturbing one.!! They don't sound remotely funny, specially if they are being used for someone as close as your wife. Its time CV's realize that not every situation needs to be completed with a one liner.. That too an inappropriate one..
Whether it KP or the CV's, there has to be an end to these one liners and someone needs to realize that..Its high time.!
