Two guys were walking down the street, and one of the guys told his friend he could talk any blond in the world into giving him a blowjob, any blond!
So the guy bet him 20 bucks and pointed to this cute blond sitting on the side of the road and said, "Alright, let's see it!"
The other guy walks up to the cutie and says, "Hi, my name's Dave, and my doctor just told me that if I didn't get a blowjob from a blond within three hours, the disease I have will kill me in, oh, let's see now, 22 minutes!"
She looked up at him with tears in her eyes and said, "You mean I could save you from dying right now?" Then she says, "Pull it out!"
Ten minutes later, the two men were laughing and patting old Dave on the back when his friend noticed the blond sitting in the alley bawling her eyes out!
So he walks over to her and says, "I would have thought you would be so happy for saving my friend's life?!"
So she looks up at him just crying her eyes out even worse and says, "I could have saved my dad!"
