Child: *drinking milk*
Farmer: Hey, what are you doing?
Child: Oh, I just milked one of your cows.
Farmer: We don't have any cows, we only have bulls.
Child: *realizes*
Old Mother Riley, had a fat cow.
She milked it and milked it but didn't know how, she pulled his tail, pulled his tits. Old Mother Riley was covered in sh!t.
