That's a bit harsh isn't it?
Olly was filming a segment for fundraiser 'Stand up to Cancer' yesterday when he was duped into thinking that a stunt featuring Aston being shot out of a cannon had gone horribly wrong.
Aston 'volunteered' himself to be shot out of a cannon and nominated Olly to press the button to set the it off.

However, as Olly Murs pushed the button nothing happened leading to the singer pressing the button again.
Aston Merrygold then appeared to shoot out off the cannon, missing the crash mat and instead colliding with the a wooden stage.
Ouch.
A panic stricken Olly looked on as Aston appeared to be lying motionless on the floor.

Olly was then put out of his misery when Aston and the rest of JLS emerged behind him, revealing that the person who had been shot out of the cannon was in fact a stuntman.
Taking to Twitter Olly wrote: "Still recovering, still shaking & still shocked!! @JLSOfficial you got me proper today!!"
Marvin Humes also posted on the social networking site following the stunt.
He tweeted: "Just did an amazing prank with @ollyofficial and lots of JLSters!! Absolutely hilarious! Can't wait for u all to see!!"
We'd watch our backs if we were JLS as we wouldn't be surprised if Olly Murs tries to wreak his revenge sometime soon.
The prank will be aired on Channel 4's 'Stand up to Cancer' on 19 October at 7.30pm.
