“Oh, brother!” is an apt description for last night’s episode of “The Tonight Show,” in which former “One Life to Live” star Scott Evans (ex-Oliver Fish) and his older bro, “Captain America: The Winter Soldier” star Chris Evans, shared some of their most hilarious childhood memories. The two played “The Sibling-wed Game” — a brother-oriented version of “The Newlywed” game — where each tried their best to guess the funniest, most over-the-top moments from their childhood. And boy, oh boy, do the siblings have some insanely funny moments from their past! Click on the jump to see them discuss some of their outrageous pranks and stories with host Jimmy Fallon. But be warned: Your abs will hurt from all the laughing!
