To quote his mum, who posted it on Reddit recently; "This is why my son is going places." Hey, there's weight to the term "Fake it 'til you make it" - and there is a certain logic behind this 6-year-old's theory... That and he should've got extra points for the sad face.
Naturally his proud (presumably) Irish mammy is going to hang it pride of place - so he can come to appreciate the level of humour.
