If you thought that the British football hooligan was a dying breed - a small, inconsequential clique of pot-bellied men sat in dusty pubs, still talking about Millwall away in '93 to anyone who will listen - then you my friend are wrong... dead wrong!
Just take a look at these madlads flying the next-gen flag.
Embracing the arrival of Everton (and Ronald Koeman's great big pink face) on Saturday, West Ham's finest foot soldiers - led by the mighty Liam, of course - posted up an oh-so-menacing warning to the Toffees' "boys."
Ok, so you've got some classic watched-Green Street-too-many-times-when-you-were-12 staples on show here, like the baseball bat (albeit covered in tinfoil?) and a rusty machete. But when you're bringing a putter and what looks like a Soviet-era farm tool - not to mention the kid who's just sort of scrunching his fingers up in place of a weapon - then you best believe the internet's going to have their say on the matter.
Here are some of Twitter's most creative responses.
Boys, boys, boys... what were you thinking?
Liam and the boys must have done something right, though - because Everton hardly showed up at all in what was a drab 0-0 encounter at the London Stadium.
The Met are lucky it was just a warning. They might not be so lucky next time.
*We reckon this whole thing was a troll job and Liam is actually comedy genius.
