The increasingly entertaining online content site, The Daily Beast, edited by Tina Brown, is getting very good at putting together juicy collections.

Besides one on “Seven Great Talk-Show Trainwrecks” recently, it has cued up a nice group of videos of past Oscar speeches in anticipation of the 81st annual awards show this weekend, analyzing what works and what does not.

The piece, by Dale Hrabi, includes a range of stars in action and inaction, with some good tips for those who are about to receive the hallowed little golden naked man.

Here are my two faves, one a do (Audrey Hepburn in 1954 with a classy and short thank you for Best Actress in “Roman Holiday”) and, of course, a big don’t (“Sacheen Littlefeather,” actually named Maria Cruz, not accepting the Oscar in 1973 for Marlon Brando for Best Actor in “The Godfather”).

Here’s a curious trend I’ve noticed developing quickly on YouTube, probably because of the acclaim that the late actor Heath Ledger’s performance as the Joker in “The Dark Knight” has garnered.

His memorably malevolent turn in the latest Batman movie is likely to result a posthumous Oscar for Ledger. But perhaps more interesting is the number of fans who are doing video impressions of his performance, acting out various scenes from the movie, and posting them online in tribute.

Here are just such few videos, including ones that are dead serious and others not so much, as well as a compilation of Ledger’s various scenes at the end:
