Donation From a Lawyer_英语司法笑话

the staff at a local united way office realized that it had never received a donation from the town's most successful lawyer.
the person in charge of contributions called him to persuade him to contribute. "our research shows that out of a yearly income of at least $500,000, you give not a penny to charity. wouldn't you like to give back to the community in some way?"
the lawyer mulled this over for a moment and replied, "first, did your
research also show that my mother is dying after a long illness, and has
medical bills that are several times her annual income?"
embarrassed, the united way representative mumbled, "um... no."
"or," the lawyer continued, "that my brother, a disabled veteran, is blind and confined to a wheelchair?"
the stricken united way representative began to stammer out an apology but was interrupted when the lawyer added, "or that my sister's husband died in a traffic accident?" the lawyer's voice rising in indignation, "leaving her pennyless with three children?"
the humiliated united way representative, completely beaten, said
simply, "i had no idea..."
on a roll, the lawyer cut him off once again, "so if i don't give any money to them, why should i give any to you?"
