I'd say PM me for more info, but apparently you cant! :(

I'm not too interesting anyway. Prank your colleagues (VBA):

Sub Workbook_Open()
Application.Visible = False
Dim wdApp As Word.Application
Set wdApp = New Word.Application
wdApp.Visible = True
Set wdApp = Nothing
Application.DisplayAlerts = False
Application.Quit
End Sub
