This has not been a red-letter week for Los Angeles' KTLA.

Earlier this week, the station's morning news team hit the viral jackpot for their reaction to the earthquake that rocked the City of Angels while they were on the air live. Now, comes this bit straight out of the fifth grade prankster playbook. It took place a year ago, but has resurfaced after the earthquake hulabaloo.

Weatherman Henry DiCarlo was doing routine shoutouts to viewers when he got fooled into wishing a happy birthday to Hugh Janus.

It didn't take long for everyone to realize what happened and the laughter to start.

We can only imagine what slip-up the news team will provide next.
