Yes, the orchid gives it away but... there is one other simple element to this sketch that kept it from seeming authentic.
Any real reporter who has ever conducted a live "man on the street" interview never lets a nut job talk for more than ten seconds.
Why? Because seconds 11 through 20 usually involve enough f-bombs to take down an island the size of Guam or a station the size of KCAL 9 in Los Angeles.
Which gets to the real theme of the sketch: "enjoy the humor, we know it doesn't look real."
