WATCH - Could this be the happiest baby in Ireland?
This seven-month-old's hysterical laughter is pretty contagious.
A baby bursting into laughter is one of the funniest and sweetest moments to witness - probably because it reminds us of how innocent we once were and of a time when jokes didn't need to be sophisticated to impress.
A new colour, shape or unusual sound would usually do the trick.
Just like Lorcan Daly from County Armagh who can't help but laugh hysterically as his father Raymond surprises him with the word "boo".
In a short video, which was uploaded to YouTube, the seven-month-old is seen bouncing and clapping his hands as he elicits short bursts of uncontrollable giggles.
It will melt even the coldest of hearts.
