Item 1 :

SO WHAT KIND OF BIKER ARE YOU?

A biker went to a bar and ordered a drink. As he sat sipping his whiskey, a young lady sat down next to him. She turned to the biker and asked, "are you a real biker?". 
He replied, "Well, I've spent my whole life on Harleys. My momma was pregnant with me when she rode on the back of my Daddy's Harley, then as a little boy I rode on the back with my Daddy until I finally got my own Harley. I've been riding a Harley ever since. So yes, I guess I am a real biker." 


She said, "I'm a lesbian. I spend my whole day thinking about women  . As soon as I get up in the morning, I think about women, when I shower, watch TV, eat, whatever, everything seems to make me think of women. "


Then she got up and left.


The biker was thinking about what just happened when a man sat down next to the biker and asked, "Are you a real biker?"

He replied, "I always thought I was a real biker, but I just found out I'm a lesbian." 

Analysis: Structural fallacies


All lesbians think about women all day: All S are P
The biker thinks about women all day:  a is P
Therefore, the biker is a lesbian:  Therefore, a is S
