This sign cracks me up. Whatever can it mean? My best guess is:
"People in love are prohibited from feeding the birds."
Other possibilities:
"Do not let your girlfriend feed the birds!"
"Don't sprinkle confetti on love-birds if you are a love bird!"
"Women in heterosexual relationships may not sprinkle magic shrinking powder on birds!"
People with necks are permitted to do all of these things, of course.
"Do not let your girlfriend feed the birds!" "Don't sprinkle confetti on love-birds if you are a love bird!" "Women in heterosexual relationships may not sprinkle magic shrinking powder on birds!"
