If you happened to catch the new Channel 4 documentary 'The Secret Life of 4 Year Olds' last night, you're probably thinking the same thing as us: 'new favourite programme'.

The series placed a group of 4-year-olds together in a playgroup and observed their behaviour and interactions.

Needless to say, there were some hilarious moments and even funnier quotes, including Nathaniel on the phone to his 'girlfriend', Jack saying 'Save the planet' when he was asked what he wanted to do when he grew up, and a prime 'that escalated quickly' moment when Charlotte threatened to tell 'Father Christmas and the Tooth Fairy' on Tia in a respectable attempt at one-upmanship.

One of the biggest hits amongst viewers, however, was the adorable Theo, whose dogged persistence in making friends with Tyler eventually paid off.


We've gathered some of the funniest tweets about the first episode below. The series continues next Tuesday on C4 at 8pm.
