Legos were my childhood before anime and video games took charge, so I kind of have a huge weakness for them.
...Nope, still love 'em either way. It's actually not that hard to walk across them without pain with enough practice.
I also embedded one in my foot once after I accidentally jumped on top of one and had to go to the doctor's office once because of that. Walked with a limp for 2 weeks and it was pure agonizing pain.
ohA floor of legos isn't that bad, you see the legos and can sort of distribute you weight correctly and across them and it's not too bad. It's the single lone lego you don't see that is so damn painful because you step on them with all of your weight without being ready.
