Last week I had a diner with a fellow Dutch IT professional where eventually PowerShell was brought up, specifically the switch statement.

Ernst (the name of that guy) told me that it was not possible to make a switch compare against more than 256 options, I said that it was possible.
To make things more interesting, I told him that I was willing to bet a crate of beer for it… and the fool accepted!
Note: You have to know that if I’m willing to bet food or drinks on something, I’m very sure that I’m right

Just now I’ve done some ‘switching’ and confirmed that I was right…
Ernst… I’ll take those beers now, thank you very much!

Here’s the code:

function Slap-Ernst ($param)
{
  switch ($param)
