My dad and I just invented this. (Actually, someone else may already have, but just let me have this!)
Pick a song.
Sing the melody out loud, only use “poop” instead of every syllable.
Other person guesses the song, and then other person picks a song and sings.
We used Jingle Bells, Twinkle Twinkle Little Star, The Star Spangled Banner, Oh! Suzannah!, all sorts of stuff.
My dad is ridiculously awesome.
