PowerShell script parameters not parsed correctly

I have a simple script which does not work:

Param([string] $Input, [string] $Output)
Write-Host $Input
Write-Host $Output

The $Input parameter does not get printed:

PS> .\Get-Parameters.ps1 "First" "Second"

Second

If I rename $Input to $Joe the script works fine. $Input is not a reserved name.

What is going on? I am perplexed.
