It's probably just me but stunts/pranks like this are my least favorite part of the show.I loved the bit in last night's episode. But I'm not sure I'd say what John Oliver did that led up to this would be considered a "prank" on Russell Crowe. Crowe was selling memorabilia in an auction, LWT bought it and donated it to one of the last operating Blockbuster stores. Doesn't seem like a prank to me. Just something silly like giving the massive train set to Scranton, PA.
(All those bits about TV anchors aren't that great either. )
