Who said 3 year-olds don't have a sense of humor

Actually, before we had kids, Mrs ERJ said that.

"Row, row, row your boat..."

Quicksilver surprised me by asking to play "Row, row, row your boat..." where I sing the song and she sits on my knees facing me. She holds my thumbs and I make rowing motions.

I was confused as she melted into uncontrollable, hysterical laughter near the end of every stanza. She shrieked with delight and gabbled away in the blurred enunciation of a three year-old (+ 8 months).

Finally it dawned on me.

"Row, row row your boat,
gently down the stream.
Merrily, merrily, merrily
life is butt a dream." 

Yes, gentle readers. She was melting into uncontrollable laughter because she had tricked "Grandpa" into saying the forbidden word "Butt" (British interpretation "Arse" or "Buttocks")

I got even when she was looking for her stuffed bunny. 

Bonus lyrics

Row, row, row your boat
Gently down the stream.
If you see a crocodile,
Don't forget to scream

Row, row, row your boat
gently down the stream.
Ha, ha, fooled you
I'm a submarine. 

Row, row, row your boat
Gently down the stream.
Grab an oar, jokes on you,
I'm out of gasoline 

I am always looking to expand my repertoire. Any other G-rated lyrics will be appreciated.
