A video of a Gravesend man downing a pint of lager, vodka, stinging nettles, grasshoppers, a spider, four mice, and milk has been condemned.
It is one of the latest videos in the latest neknomination social media craze, which is reaching ever increasing levels of absurdity.
Now animal charity the RSPCA has criticised those who use animals in the drinking stunts.

Aaron Johnson downs the drink of spiders, mice, lager, vodka and milk in a neknomination challenge
Aaron Johnson, 24, uploaded the video showing him mixing two different lagers and vodka together before placing them into a food processor.
He then adds stinging nettles, which he says are eaten by grasshoppers, bought from Pets at Home, which are eaten by the spider he then adds, followed by four dead mice.
The items are then blended and the gloopy mixture is poured into a pint glass and downed, while his friends film it.
Once downed, Mr Johnson spits a mouse bone into the sink before nominating his friends.

Mr Johnson, posting on the Gravesend Messenger Facebook page said: “I loved every minute of it. There was no gun pointed at my head.
"I did spend an hour picking mouse bones out my teeth."
Should this craze be condemned?
Insects and spiders do not fall under the Animal Welfare Act, and the mice were dead before being eaten, and therefore everything is legal.
The neknomination craze is believed to have started in Australia and involves someone downing a pint - with the ingredients chosen by the nominator.

That person then nominates others to do the same within 24 hours.
Other people from Kent have posted clips of them eating cat food, fish heads and even adding urine to the concoctions.
“We would like to remind people that this is not a light-hearted joke or entertainment, it is cruel and unacceptable" - the RSPCA
Videos from across the country have purported to include live animals and the RSPCA says it has been inundated with calls from people concerned about the new trend.
A spokesman said: “We would like to remind people that this is not a light-hearted joke or entertainment, it is cruel and unacceptable.
"You could be prosecuted under the animal welfare act and could face up to six months in prison and/ or a £20,000 fine.
“We want to send a clear message to people that animal cruelty is never OK, even if it is in the guise of ‘entertainment’.

“The RSPCA would urge anyone considering taking part in this awful craze not to, and appeal to the public to report anyone to us who has been involved in a neknominate video involving a live animal.”
Strood GP Dr Julian Spinks condemned the craze.
He said: "I think this is a very dangerous thing that is happening.
"It's an almost lethal combination of alcohol - combined with that feeling teenagers and young people have that their indestructible, means they'll do something which potentially could kill them.
"A lot of this is dependent on drinking large amounts of alcohol at one time, especially spirits.

"You're getting people who're drinking 30 or 40 units in a single drink. That can put levels up to the point where alcohol becomes poisonous which can lead to not being able to breath properly and even coma and death.
"My feeling is that with the mixtures of things you're drinking, you can not predict the effect and as a result there's a danger and you really shouldn't be doing this.
"Alcohol is the obvious risk from a medical point of view, but if you're putting other things in there's a risk they may be poisonous as well or the combination of things may cause an effect you're not expecting."
