PowerShell - Speak random cat facts (https://www.reddit.com/r/PowerShell/comments/6550a7/using_powershell_for_office_pranks)

catfacts.ps1

#Run this every 1/2 hour and in an 8 hour work day there will be approximately 3 times per day that your victim hears a cat fact
if ((Get-Random -Maximum 10000) -lt 1875) {
    Add-Type -AssemblyName System.Speech
    $SpeechSynth = New-Object System.Speech.Synthesis.SpeechSynthesizer
    $CatFact = (ConvertFrom-Json (Invoke-WebRequest -Uri 'http://catfacts-api.appspot.com/api/facts')).facts
    $SpeechSynth.Speak("did you know?")
    $SpeechSynth.Speak($CatFact)
}   

That API seems to be kaput sadly ;n;

I get the following error:

Invoke-WebRequest : Python 2.5 is no longer available. Please refer to https://goo.gl/aESk5L for more information

But I found another API that works and wacked that into your script...

#Run this every 1/2 hour and in an 8 hour work day there will be approximately 3 times per day that your victim hears a cat fact
if ((Get-Random -Maximum 10000) -lt 1875) {
Add-Type -AssemblyName System.Speech
$SpeechSynth = New-Object System.Speech.Synthesis.SpeechSynthesizer
$Random = Get-Random -Maximum 200
$CatFact = (ConvertFrom-Json (Invoke-WebRequest -Uri http://www.catfact.info/api/v1/facts.json?per_page=200)).Facts[$Random]
$SpeechSynth.Speak("did you know?")
$SpeechSynth.Speak($CatFact.details)
}

This is such a novel idea I love it. I'm going to include it in my PowerShell course I'm teaching to try and get the old curiosity peaked.

Both APIs are now out. So here's the script with another API that seems to work for now:

#Run this every 1/2 hour and in an 8 hour work day there will be approximately 3 times per day that your victim hears a cat fact
if ((Get-Random -Maximum 10000) -lt 1875) {
Add-Type -AssemblyName System.Speech
$SpeechSynth = New-Object System.Speech.Synthesis.SpeechSynthesizer
$Random = Get-Random -Maximum 200
$CatFact = (ConvertFrom-Json (Invoke-WebRequest -Uri https://catfact.ninja/fact))
$SpeechSynth.Speak("did you know?")
$SpeechSynth.Speak($CatFact.fact)
}

Wrote an on-demand function for the fun of it.

function get-catfact {
    param (
        [switch]$say
    )
     [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls12
    
    $catfact = (convertfrom-json (Invoke-WebRequest -UseBasicParsing -Uri https://catfact.ninja/fact)).fact

    if ($say){
    Add-Type -AssemblyName System.Speech
    $global:SpeechSynth = New-Object System.Speech.Synthesis.SpeechSynthesizer
    $global:SpeechSynth.Speak("did you know?")
    $global:SpeechSynth.Speak($CatFact)
    } else {
        $catfact
    }
}
