A Japanese man has hilariously pranked his grandmother after taping himself to the ceiling of their family study and evading her attention for more than an hour.
The man's practical joke went viral after he dressed in a full-body morph suit and suspended himself above the room using his grandfather as an accomplice.
The elderly relative was blissfully unaware of the daring prankster until she finally realised her daring grandson was staring ominously at her from directly above.

Sharing his grandmother's screams of shock with his millions of YouTube followers, the man said he wanted to know how long it would take for people to notice him camouflaged on the ceiling.
The video starts with his test bunny for the experiment entering the room and watching his grandfather watch videos on his computer.
Much to the prankster's surprise, his grandmother still fails to notice him even when his accomplice asks her to put pancakes on the table.

She then leaves the room for ten minutes before returning again and sitting right underneath her grandson while doing the laundry.
It was only then she realised the human being strapped to a ceiling panel above her, screamed out and grabbed her head with a pair of socks as if to protect herself.
'What is it?' the grandmother asked the grandfather who is waiting outside.

'It took too long for you to notice me!' the YouTube prankster called Riku replied.
'How long did you leave me stuck to the ceiling? My neck has reached the limit of endurance already!'
But rather than being furious at her grandson's mischief behaviour, the grandmother asks for him to forgive her for keeping him waiting for so long.

'How did you not get a headache from staying in that position for so long?' another added. 'I gave you a like because you deserve it!'
