my kids were very good at mishearing.
my little daughter used used to love the the (BEE_GEES?) song LOVE IS THICKER THAN WATER. however, she would sing LOVE IS SUCKERS IN WATER.
and my son didn't sing much but when just about a year old would try to imitate my husband and pray before he would eat. but instead of directing his prayer to Jehovah, his prayer went like this... HERBERT, AMEN. short and sweet, huh?
