This one has always driven me crazy.
In SLAV, after Clark resuces Lois, the whole charades thing is bad enough, but then he has to stop the bomb from going off at the peace talks which are miles away in Metropolis. He throws a piece of (glass, mirror) high into the air, fires his laser vision at it. The Laser vision bounces off and refracts directly to the building where the bomb is. Let's say, he got lucky and it passed through a window on the exact floor of the bomb, so the laser vision didn't blow a hole in the side of the building and it didn't refract off the glass as it had just done. But then, the bomb is under a heavy wooden table. The laser vision somehow gets under the table and burns out the bomb mechanism without damaging the table or exploding the bomb. It's just too unbelievable to be funny. At least the huge canister-full-of-liquid bomb, instead of some small plastiquie device, under the table in WHALTTA was so ridiculous it was funny, intentionally so.
