They got to talking about what they got their wives for their last anniversaries.
The doctor took sip of his martini and said I got my wife a diamond ring and a Mercedes. That way if she didn't like the diamond ring, she would know how much I love her because of the very expensive car I bought her.
The lawyer took a sip of his scotch and said I got my wife a pearl necklace and a trip to the Bahamas. That way she would know how much I love her, even if she didn't like the necklace.
The biker took a big swig of his beer, farted, and burped, and said I got my wife a Harley t-shirt, and a vibrator. That whay if she didn't like the shirt she could go "F" herself.
