Bedtime laughs

Sometimes my Mom abilities need some fine tuning!

Tonight at bedtime I was trying to sing the boys a song.

Me: "Row, row, row your butt........ Wait...."

Adam: "You said butt! Row, row, your butt! Hahahaha."
Matthew: "Row, row, your butt!" "Hahahahaha""
(Repeat x35)

Me: "No, no, let's sing it right!"

"Ok!"

Adam: "Row, row, row your BOAT, gently down the Butt!"

I give up :P
