The Gumshoe

The 13 year old boy finished showering, dressed for bed and went to his room.



Shortly thereafter his 10 year old sister entered the bathroom and was heard shouting to her brother "Didn't your mother teach you how to flush?!"



The boy replied sharply, with indignance, "I didn't use the toilet!"



The girl, considering that possibility for a moment, quickly disgarded the thought and shouted back "Girls use toilet paper. Can you explain why there is pee in the toilet but no toiletpaper?"



Kids are funny!
