Germanfag here, here's a translation:
Camera guy: "Yeah, you can do it now."
Second Guy: "You Can't Do That" (in a particularly bitchy tone)
Camera guy burps
Third guy "You can't be serious."
Camera guy "Good thing noone knows...the silicon spray can is getting so hot!" (this rhymes in german.)
Second guy, laughing "Hey, oh boy"
Camera guy: "That...that was it? That was just the silence before the storm, Haha"
The oven explodes.
Camera guy: "Oh shit" laughing "Oh...shit"
And then they're all just giggling and saying "Shit" and "Oh god"
