Some funny sightings I found that people sent me. Are these people for real?

IDIOT SIGHTINGS

Idiot Sighting #1:

I was
at the airport, checking in at the gate, when the airport employee asked, "Has anyone put anything in your baggage without your knowledge?" I said, "If it was without my knowledge,how would I know?" He smiled and nodded knowingly,"That's why we ask."

Idiot Sighting #2:

The stoplight on the corner buzzes when it is safe to cross the street. I was crossing with an intellectually challenged co-worker of mine, when she asked if I knew what the buzzer was for. Iexplained that it signals to blind people when the light is red.She responded, appalled, "What on earth are blind people doing driving?"
