Do you know who Giada de Laurentiis is? She's the host of Everyday Italian on the Food Network, who also happens to be a super hot chick with great cleavage. But she consistently demonstrates one of my biggest pet peeves, and this unfortunately really prevents me from liking her.
The pet peeve can be seen in the following video:
You only have to watch until second 27. If you do, you will notice that Giada speaks English with a perfectly flat American accent, and yet, when she pronounces the word "gelato" in second 26, all of a sudden, you hear a very surprisingly sudden burst of Italian accent.
I have noticed that a lot of people do this, that is, pronounce foreign words with a put-on foreign accent, apparently to show off the fact that they took French in college or went to Quebec City and stayed in a Holiday Inn once. Make it stop.
