The Daily Grind: When do levels get ridiculous?

Level 80. Level 90. Level 100. Level 310. Some games have a level cap that only goes up to 50, while other games sometimes have level caps that send you into the upper 100s. What's the difference between a level 50 capped character and a level 100 capped character? Sometimes, it's not much at all.

So here's today's question: When do level numbers begin to seem silly to you? Is level 80 pushing the bounds of too many levels, or is that thought specifically reserved for level 90? Is it a higher number? Or do level numbers cease to phase you at all at this point, as you've leveled enough in all of your games to be considered as level eleventy billion?
