The thoughts of your every move being broadcast to the nation in real time is terrifying. What if you sneeze? What if you get stage fright and can't think of what to say to your guest?
Or what if, you get such a fit of the giggles that you go into convulsions live on TV?
That's exactly what happened on TV3's Ireland AM on Valentine's morning when mixologist Darren Geraghty joined Alan Hughes and co-presenter Ciara Doherty to make some special cocktails.
All was going well until Darren was explaining how to make the Love Spell, saying "this is actually a special drink as I designed this drink for my girlfriend."
Without thinking, presenter Alan quipped "when did you first give it to her?" and they just BURST into laughter.
They're in hysterics... We're in stitches just looking at them
The poor duo couldn't keep it together and even the cameramen can be hard laughing for the entire segment.
They then had to cut to a break as they wiped away the tears of giddiness from their eyes: "We have to take a break, we have to…goodbye..."
Watch the full thing and just try not to be in bits laughing:
