What would happen if Superman passed gas?

I have spent several sleepless night pondering this question. Superman has superhuman powers capable of tremendous damage if used haphazardly. On Smallville, Clark sneezed and nearly destroyed the barn I believe. What would happen if he passed gas after a delicious but gassy, Mexican meal? I need input from physic majors on this one.|||Earth would be blown out of orbit.|||He did, all through the last movie....it stunk|||ohhh hell, kinda like armageddon i guess....but bad non the less...lol|||It would be gross.
