The folks at Dragon*Con TV have released yet another of their humorous videos that play on all the panel screens while people wait in line and such at Dragon*Con 2011.

The latest video features members of Marvel’s most powerful superhero team The Avengers trying — and failing — to produce a public service announcement advising children not to do drugs.

The humor of this situation — as many long-time fans of the comic book know — is that Tony Stark (a.k.a Iron Man) is a recovering alcoholic while the team’s star spangled leader Captain America owes all of his powers to experimenting with drugs.

D*CTV, the good folks who provide video entertainment to the 40,000 convention attendees at Dragon*Con, has released a new sketch that picks fun at two characters that are either extremely loved or extremely hated the world over: Edward Cullen and Bella Swan.

Below is the video they produced parodying the 1989 romantic comedy When Harry Met Sally — only using the two most popular characters from Twilight.

From the video description:

There are certain things people should just avoid doing at a convention, like not showering, invading personal space of others, and publicly wearing a fury costume. Since the anal retentive geeks in attendance usually choose to ignore any rule that isn’t explicitly stated, it can very well ruin the experience for everyone.

The guys from Dragon*Con TV, who also produced the “Vaderex” parody we reported on last week [READ: Watch Now: “˜Vaderex’ Is A Prescription Drug Proven To Reduce Dark Side Flare-Ups In Jedi], decided to make a public service announcement at Dragon*Con to target just those types of geeks.

Think of it as sort of a “Best Practices” or Con Etiquette for the masses.

The video is playing in between panels and addresses religious conversations, personal hygiene, inappropriate random sounds, Robots, Zombies, and much more…

Check out the video embedded below and share with friends who’ll be at a convention in the near future.

Try explaining midichlorians to someone unfamiliar with the Star Wars films and it may come off sounding like a sexually transmitted disease.

Building upon that logic, the folks who produce Dragon*Con TV decided to make an interstellar PSA for Jedi who want to live a normal life despite their “condition.” While there is apparently no cure for “Midichlorians,” prescription drugs do exist that can reduce the number of Dark Side flare-ups and curb symptoms.

According to the video, embedded here below, the prescription drug Vaderex can help.
