A guy sees a classified ad that says “I will give you a blowjob while singing ‘Take me Home Country Roads at the same time’. “
The guy thinks to himself that it sounds interesting and unbelievable, and so decides to pay her a visit.
She lets him in and says that the lights have to be off.
So she turns the light off and starts sucking his dick.
All of a sudden he hears ‘Take me Home Country Roads’, clear as day.
He really wants to know how she is doing this so he flips on the lights.
All he sees on the floor is a glass eye.
