At the 2009 Oscars on Sunday, Ben Stiller hilariously spoofed Joaquin Phoenix’s infamous appearance on The Late Show With David Letterman.

The 43-year-old comedian poked fun at Joaquin’s facial hair, his spacey moments and gum-chewing. At the show, Ben spit out his gum and put the wad on top of the podium. During rehearsals at the Kodak Theater the day before, I watched Ben stick the wad of gum underneath the podium, more true to Joaquin sticking his own piece of gum underneath Letterman’s desk.
