The Dave Effect 

A release of endorphins in the brain which causes weakness of knees and sexual tension in females and a desire of emulation in males. It is brought on by the presence of, thought of, or mention of The Dave.

As Gary mentioned Dave, Daniella felt her knees go weak and knew she was experiencing the Dave Effect.

The Dave Effect 

The phenomenon that causes females to be repulsed by the mention of Dave. It is believed to be triggered by Dave's chronic knowitallism and overall weirdness. Other possible causes include a funny smell, a funny face, and a geeky demeanor.

"Hey Sarah, do you know Dave?"
"Ew, don't even say that name. It gives me the heebee jeebees."

The Dave Grohl Effect 

Most prominent in the frontman of the Foo Fighters Dave Grohl (and thusly named after him), the Dave Grohl Effect is when a man looks far, far better when he has a beard. Examples of more people the Dave Grohl Effect works on are Sean Bean, Alec Baldwin, Will Wheaton, Martin Freeman and David Schwimmer.

"Hey, have you seen Joe? He's really rocking that new beard, makes him look totally badass"

"Yeah, that'll be the Dave Grohl Effect."

The Dave Coulier Effect 

Dave Coulier played a professional comedian on Full House, yet he was the least funny character on the show. The Dave Coulier Effect is when someone should be/acts like an expert on something, but is actually clueless on the subject.

The HR guy drives me nuts! He's suffering from The Dave Coulier Effect.

the dave chappelle/rick james effect 

It happens whenever something funny is presented, then wholly gobbled up by the media and public, excreted into senseless dreck, and then whatever originality and humor was left in the original source of material, has been thouroughly raped into bleeding submission.

Eg; whenever someone says "I'm Rick James B*tch", or anyone makes a quote from Napoleon Dynamite. Particularly "Gosh", or something along those lines.
