I just got blasted, in the middle of a geology class, by a Pedigree dog food ad at the bottom of the main page. It leads to their facebook page: https://www.facebook.com/PedigreeTreats
Seriously, my professor was in the middle of a power point that I wasn't paying attention to when it went off, at full volume. Had no idea how to turn it down. I haven't been that embarrassed in a long time.
I feed my dogs Pedigree. Good stuff.
