The two young men obviously know each other well.
The video shows them joking and jostling amongst themselves as they walk along West End streets at night.

It's Friday, April 15, 2011, between 10.30pm and 11pm and the pair are the centre of attention in the police CCTV video.
One man is wearing light pants - possibly jeans - and a dark T-shirt with a lighter-coloured emblem right in the centre of his t-shirt.
His friend is wearing dark pants - also possibly jeans - and a darker shirt. They light-heartedly grapple and wrestle each other as they walk along.
Nearby, at 10.30pm, a young woman leaves left the Uber nightclub on West End's Boundary Street to walk to her bus and go home.
Sadly, their paths will cross.
The young woman is 20 years old. She has long dark brown hair. She is wearing a smart black-patterned top with an embroidered front panel and a dark skirt.
She leaves the upstairs Uber nightclub and turns right. The club is directly opposite the Boundary Hotel.
She walks down Boundary Street past the old West End police station in the old timber house, past the pizza place, the bars and the takeaway restaurants.
She is wearing sandals as she walks along the footpath towards the Melbourne Street intersection.
About 10.40pm, the woman sees the two men at the intersection of Boundary Street and Melbourne Street for the first time.
"A few minutes later the woman has encountered the two men outside a prominent café on the corner of Browning and Boundary streets in West End," a police re-enactment released this week says.
The Melbourne Hotel is 100 metres away towards the right.
About 10.45pm, the woman crosses Browning Street, followed closely by the two men. She walks down Melbourne Street towards the city.
The two men are closely following her. She can hear them following her and notices them slowing as she slows, and walking faster and she walks faster to try to get away from them.
She tells police she was terrified by this point.
About 10.50pm, the young woman nears the intersection of Manning and Melbourne streets. It is almost where West End becomes South Brisbane. A prominent hairdresser's headquarters is close by. Directly across Melbourne Street at this point today – five years later - is a juice bar.
Down Manning Street to the right is Musgrave Park. Directly across Manning Street is a restaurant that older residents will recognise as the older Squirrels Restaurant corner. Squirrels is long gone.
About 11pm to 11.30pm: Just before she gets to this Manning Street corner the young lady is forced into a narrow alley and attacked by two men, the police re-enactment says.
"Finally the woman was forced by the two men into an alley just before the intersection of Melbourne Street and Manning Street."
Here she is sexually assaulted by both men, police alleged as they re-opened the cold case this week.
She suffered "severe internal and external injuries", according to police.
Detective Senior Sergeant Tim Leadbetter said the crime was horrible.
"This is one of the most serious sexual offences I have come across in my years of policing," he told reporters.
The late Inspector Rod Kemp said at the time the woman "was aggressively raped in the worst way I have seen in my service" and "animals don't do that to each other".
In 2011, after the first public appeal, a lot of information was received from the public, but no arrest was made.
This week, Detective Inspector Garry Watts said forensic information that was received in 2011 will now be re-tested using modern techniques.
He called again for public help to help corroborate information.
"I think someone knows something and I certainly appeal, if you know something about this incident, please contact the police," he said.
Inspector Watts said police were examining similar offences in the area.
Fairfax Media has taken the approximate times from the police re-enactment released last week.
