Or the moment your Thresh throws the lantern a teemometer too far and you die before you can reach it. 
I had the worst timing once as
with a thresh. I was on low health and decide to go out in glory ( or jump on one than try to escape I can't remember which), I go to jump one of them (To the skies I think) over a wall by the red buff and just as
throws his lantern at my originally spot. I try to get back annnd I die. No way
fault, or mine, just the timing involved I found ironic.
what's even worse is when they finally grab the lantern but then they flash back into the enemy team
