Well, NEARLY effortless.
Sidney Deane and Billy Hoyle from White Men Can't Jump.
Why it's easy: You could walk into any thrift store or Urban Outfitters and find everything you need for these costumes.

Possible Downside: You have to backup all your shit talking.
Conor O'Neill from Hard Ball.
Why it's easy: All you need is a leather jacket and an aura of scumbag.
Why it's awesome: Who doesn't want to be a degenerate gambler for one night? Also you get to date Diane Lane as a school teacher!
Possible downside: Finding a bunch of 11-year-olds who will be the Kekambas.
Shooter McGavin from Happy Gilmore.
Why it's easy: All you need is a polo shirt and a superiority complex.
Why it's awesome: You get to be the greatest villain in sports movie history.
Possible downside: You might get your ass kicked for simply being an asshole in a polo shirt.
Spike's dad from Little Giants.
Why it's easy: Wear dark military-esque t-shirt. Pour water all over your shirt. Be very demanding.

Possible downside: People constantly doing pull ups on your arms.
