Dumping a bucket of ice water on one's head is nothing when compared with competing in televised blood sport against children, so we're glad to see the "Hunger Games" boys doing the right thing for ALS. Josh Hutcherson, Liam Hemsworth, and Sam Claflin (who play Peeta, Gale, and Finnick in the films), have all taken on the Challenge over the past few days, with Hemsworth even dressing up as a Ninja Turtle in the name of charity.

Hemsworth was up first, and he nominated Woody Harrelson, Hutcherson, and Matt Niven to go next. His costar Hutcherson quickly accepted, and he nominated his third grade teacher (awww), his first acting teacher, and another teacher, Pat Jackson.

Claflin then took the Challenge in "rainy" London, and all of this was so adorable but it also begs the question, "When the heck is one of them going to nominate Jennifer Lawrence?"
