Happy Birthday, Garrett Ryan! From solving twisted mysteries on *Criminal Minds* to unraveling forensic puzzles on *CSI: NY*, you've mastered the art of looking serious while secretly plotting your next snack break. Your performances have kept us glued to our screens—partly because we're impressed, and partly because we can't figure out how you manage to look so cool under pressure.Here's hoping your birthday is filled with fewer crime scenes and more cake scenes. May this year bring you roles as thrilling as your past successes—and may none involve running from fictional serial killers (unless you're into that sort of thing). Cheers!
