I guess it depends on how you define "forcing it." Keep in mind, sometimes players do things that are ridiculous in context of what the GM knows about the situation that the players may not. For example, I lived in Salt Lake City for several years as a child, and therefore know a lot more about snow, ice and skiing than my players in later years who all grew up on the US Gulf Coast. When a player tries to jump from a pair of skis onto the back of a dragon, I'm perfectly comfortable with expressing the result in a way that makes him aware of just how ridiculous his attempt was.
That and there's a certain amount of "gallows humor" involved in gaming. The obvious example I can think of is the time an opponent was using a wand of lightning during a battle in tall grass prairie in summertime, and failed his roll catastrophically. He not only lightning bolted himself, he started a brush fire. Yeah, there was a lot of sick humor involved in that session, in much the same way that there's a lot of sick humor among soldiers in a war zone.
