Ah, the perils of live television.
KTLA Morning News weatherman, Henry DiCarlo, got caught out by a prankster during a live television segment where he usually gives viewers a shout out.
Henry was going about his business wishing 10-year-old 'Hugh Janus' a Happy Birthday until news anchor copped that it was a trick name and went into hysterical laughing.
It seems that Bart Simpson is alive and well!
