How "Lucky" is a lucky sim, really?

@MKSizzle - The cooking thing is not absolute, it's a random event which is chanced higher on the cheaper stove. I have had Sims torch not just their food but themselves on the cheapest six-eyed stove in the game, lesser on the cow poke stove or above. The only Sims who are immune to this is one with the 'Natural Cook' trait. For every other unskilled or low skilled Sim there is a chance it could happen; lucky changes those odds a bit higher in favor that it won't happen to your Sim; it still could.

Okay, I'm missing the 'irony' part (just me), because the trait is basically a 'chance' trait with the chances for good things to happen being slightly higher for the Sim with this trait in comparison to a non-lucky Sim. Unless you meant irony of your Sim's life and not the trait itself, in which case I'd have to agree. :)
