From 17-0 down to 26-20 ahead, Ireland's young guns are making a habit of this comeback lark.
Nigel Carolan's men were right up against it, on Tuesday evening, when they trailed Wales in the U20 World Championships opener, in Manchester.
The Welsh beat Ireland well on their way to this year's Six Nations Grand Slam and were primed to repeat the dose. That was until tries from Ulster duo Adam McBurney and Jacob Stockdale gave them hope.
Munster's Bill Johnston chipped in with scores from the kicking tee and Stockdale got over in the corner to stun Wales. They responded with a late try but the difficult conversion miss sealed Ireland's 26-25 win.
Up next, New Zealand on Saturday.
Captain James Ryan and his teammates are starting to believe in their game-plan, and talents, so anything is possible.
