A new twist to a familiar tune

Daniel came into my room yesterday morning and asked to use the bathroom. He hopped up and sat and sat and sat and sat. After about 10 minutes (I was dozing in bed) he shouted that he was done... and then proceeded to sing the word "Done" to the tune of The Star Spangled Banner! Probably a little unpatriotic or something, but VERY funny. I ignored him for a while and he just kept on belting it out. He sure is good at finding ways to amuse himself.
