was this one already posted?:
there was a really fat boy and whenever he went out and the father offered him a piece of cake he always said, “yes” and the shidduch never went through. every time the shadchan begged him not to eat anything but to no avail. then one night the shadchan pleaded and pleaded and he said, “okay. i wont eat anything” that night he stuffed his face full. the shadchan was horrified “i thought you said you wouldnt eat anything” to which he replied”i already decided the girl wasn’t for me might as well get the free food”
