The Mortified Sessions premieres tonight at 8pm

A young Will Forte

What would we find if we opened up your secret shoebox of middle school memories or leafed through your high school journal? The sometimes humiliating and often hilarious reminders of our past are revealed in “The Mortified Sessions,” a new Sundance Channel original series that reveals mementos from celebrities’ past to shed light on who they are today. Awkward childhood photos, profane diary entries and embarrassing poetry take center stag as our favorite actors share their personal artifacts and anecdotes of their youth.

On tonight’s premiere episode, Ed Helms unearths some nerdy rock lyrics he wrote in high school. Find out how embracing his inner geek put him on the road to comic success. And Oscar winner, Mo’Nique reveals the childhood lessons that convinced her to never give up on her dreams. Then Eric Stonestreet (“Modern Family”) reminisces about his unusual childhood in Kansas. Find out firsthand why he loves clowns, and share stories from some of his surprising after-school activities, including pig-raising contests and fashion modeling at the mall.

Tune in tonight at 8:00 and 8:30, and see the full schedule.
