Some old men were caught watching a pornographic video in a public transport locally known as "trotro".

A co-passenger who shared the video on Twitter, said the men are obviously in their 50s and they had a "swell time" watching porn in the front seat of the commercial vehicle they sat in.

The incident reportedly happened on a bus in Lagos State, Nigeria.
