A home video of two babies engaged in an animated conversation in a kitchen has become an Internet phenomenon.
The two-minute clip shows twin brothers Sam and Ren McEntee, aged just 17 months and barely able to stand, enjoying a lively exchange in which they laugh, raise their hands emphatically and nod their heads.
So far the footage has attracted a staggering 9.4million views on YouTube.
Online hit: Twins Sam and Ren McEntee, aged just 17 months, enjoy a lively exchange in which they laugh, raise their hands emphatically and nod their heads
This is probably because the boys' conversation is so adult in its mannerisms and they appear to genuinely understand what each other is saying.
Transfixed viewers even made suggestions as to what the brothers might be talking about - before comments on the video were disabled.
Suggestions had included one brother telling the other 'That diaper is so 2010', before receiving a response of 'If you're so smart, where is your other sock, Einstein?'
The babies' mother Abby has a blog, twinmamarama.com, on which she writes about her experiences as a twin sister raising twin boys.

Mrs McEntee wrote on Wednesday: 'We've had a fascinating time seeing language blooming around here. Now the experts weigh in on this kind of twin language.
'I remember my own folks talking about my sister and I sending out verbal signals (essentially squeaks and shouts) in an attempt to pinpoint the location of our twin sister around the house!'
Child development specialists have even chimed in to say how natural and healthy it is for babies to develop language skills as they mature.

Professor Karen Thorpe, of the Queensland University of Technology’s School of Psychology and Counselling, told ABC News: 'Babies are wired for communication from the start and we see here a fine example of how sophisticated and beautiful communication in even young children can be.'
The broadcaster also reported that 40 per cent of twins develop what appears to be their own language.
However, they are mimicking sounds and mannerisms that they have heard or seen, rather than actually understanding what each other is saying.
