I recently got into an argument with my friend about this... he’s from NY and I’m from MO so that might explain the difference

Haven’t seen my version of down by the banks ANYWHERE! Very weird

I learned it in Girl Scouts/general elementary school

Down by the banks of the hanky pank
Where the bullfrogs jump from bank to bank
Singin fee fo fum
Hee-say mee-say
Ding dang dong (out on dong)

Dr.Pepper came to town,
Coca Cola knocked him down,
7 up caught the flu,
Now we’re drinking Mountain Dew,
Mountain Dew fell off the mountain,
Now we’re drinkin from the fountain,
Fountain broke,
Now we have nothing to drink (out on drink)
