"If anything is possible, is it possible for anything to be impossible?"
"If someone with multiple personalities threatens to kill himself, is it considered a hostage situation?"
"If you try to fail and succeed, then which have you done?"
"Why is 'abbreviated' such a long word?"
"Why is a boxing ring square?"
"Why is it that rain drops but snow falls?"
"Why is it that when you're driving and looking for an address, you turn down the volume on the radio?"
