There's only one thing to do when you have quadruplets, make home videos of them laughing hysterically. That's when you're not rushing around changing four times as many nappies and preparing four times as many bottles, of course.
In the early 2000s, the Mathias family - most notably their identical quadruplet baby girls - took the world by storm when they appeared on America’s Funniest Home Videos.
Sat in their mother's arms Grace, Emily, Mary Claire, and Anna are unable to suppress their laughter as their father goofs around behind the camera. And their giggles are truly infectious.
The video has won the family thousands of dollars, including $250,000 prize in 2006 for the “Funniest Video of All Time”.
Sure the foursome are cute when they giggle, but imagine what it must be like when they cry in unison... *shudders*
