Things that make you go d'oh!

[TheydonBois]

While taking the new Viglen PCs at our school and complaining to the ICT teacher that the side grills that say 'Do not cover' may as well say 'this is how you break me'. I say someone could pour a drink down the grill like this, picking up what I thought was an empty cup on the teachers table and making a pouring motion, slightly tip the cup up.

 

It wasnt, but thankfully it splashed on the side of the table.....
