A man calls a lawyers office.
The phone is answered: 'Schwartz, Schwartz, Schwartz and Schwartz!'
The man says: 'Let me talk to Mr. Schwartz!'
'I'm sorry, he's on vacation!'
'Then let me talk to Mr. Schwartz!'
'He's on a big case, won't be back for a week!'
'Then let me talk to Mr. Schwartz!'
'He's playing golf today!'
'Okay, then let me talk to Mr. Schwartz!'
'Speaking!'
