If you need cheering up, look no further than this adorable video of two babies laughing hysterically as they play with some rubber bands.
Whilst parents may spend plenty of time and money trying to entertain their little ones - it seems that the real solution is actually quite simple - a couple of elastic bands and a cupboard door.
These two character's giggles are utterly contagious and we promise you'll be laughing yourself by the end of this cute video clip.
The pair are having so much fun with their little game they completely fail to notice now many times they bang their heads on the floor.
But just WHAT exactly is so funny?!
