How many hands does it take to learn?

Sven is getting over a cold. We kept him home from school for one day, but the next day we told him he had to go back. Sven shook his head and said "no, I can't go to school, I have to blow my nose." When I told him he could blow his nose at school he said "But, I need both hands to learn."

Sven's cold has also produced some funny rhymes. After getting an upset stomach from too much mucus he said "snot in the tummy is not funny." His ears are also plugged which led to "fluff in my ear, I can't hear."
