And he therefore brands him in the same category as Neymar, who also makes him laugh but in a different way - through some of his on-pitch skills.
Lanzini was opening up about a few of the off-field aspects of his life at Upton Park.
The Argentine told the West Ham site: "During training Cheikhou Kouyate always makes me laugh, he’s crazy! It’s slightly different but some of the things Neymar can do on the pitch also makes me laugh, he’s that good."
West Ham travel to Everton on Saturday afternoon and a trip to Goodison Park is always one of the tougher tests the Premier League can offer up if the Toffees are on form.
The Hammers are in form themselves, of course, and have ground out two precious wins in their last two games.
Neither victory was free flowing but rather borne out of hard work and physicality. That should hold Slaven Bilic's men in good stead this weekend, though, as Everton - like Tottenham - prefer to get the ball down and play, meaning they can easily be bullied off the ball.
