I just went on a date with a woman in a wheelchair.
I stood her up, which made her fall for me. At first it was a drag, but now we’re rolling.
Listen here, you chucklehead. You see how this works? The author is a silly goose who says he 'stood her up', which is also how she ended up on the floor when she 'fell for him'. Then he makes another funny by talking about 'rolling' when she is in a wheelchair. Get it now?
