He wandered around in search of a more accommodating girl, but was refused time and time again. Eventually he found a more sympathetic lady who told him that although she could not possibly accept his offer herself, he could try Mabel down the road. But she warned him not to expect too much as Mabel was very unresponsive and would probably just lie there passively.
He found Mabel, and as times were hard she reluctantly agreed to accept the 50 cents and the pair of sneakers for her services, but told him not to expect any kind of response from her. Mac began the amorous act and after a few minutes was pleased to find an arm coming around his back. This was followed shortly after by a leg curling around his rear.
Mac, who had always fancied himself a bit of a Romeo, gasped, "I knew you wouldn't be able to resist my charms."
"Don't worry about me, love," answered Mabel, "I'm just trying on them sneakers."
Alternate ending:
'So he finds Mabel and tells her all he has is fifty-cents. She quickly replies, 'Not to worry! I have change.'
