For a parody video sponsored by MTV After Hours, "True Blood" actor Joe Manganiello introduces "Joe Manganiello's Guide To Pronouncing F*cked-Up Celebrity Names."

The advertisement for the tutorial DVDs starts off with a couple deciding to do a movie night. The two both agree to see a film with Charlize Theron. However, they can't seem to agree on how to pronounce her name. This is when Manganiello comes to the rescue as he usually does on "True Blood."

"Hi, I'm Joe Manganiello and I have one seriously weird ass name," says the werewolf hunk. "I mean just look at it, there's a 'i' in it and all those 'ls'," he added, looking at the caption of his name appearing underneath him.

The skit also features celebrity testimonials of celebrities who thanks Manganiello for his help.

"Before Joe everyone pronounced my name incorrectly," said Rupert Grint of "Harry Potter," who appeared to be on a movie set wearing a dog collar. "Thanks to the tape they now pronounce it right."

Cee Lo Green also chimed in saying, "People use to mispronounce my name all the time calling me 'Chee Lo Green' until Joe came along. Thank you werewolf guy from 'True Blood'."

What's so funny about it is that he is actually teaching people to say these famous names absolutely wrong. For example, instead of saying "Brad Pitt," Joe suggests to pronounce it like "Bred Pitte" with somewhat of a French accent. When helping the couple with saying Jennifer Aniston's name, he totally changes her name to Rachel, the character she played on "Friends." As for Lady Gaga's name, Joe just starts beat boxing.
