2.) My favorite part about Sunday's strip? Sheldon collapsing on Legos. Speaking as someone who worked at Mattel for 8 years, I can tell you that Legos are probably the most amazing toy of the 20th Century. They will still be around long after Barbie, Hot Wheels, Cabbage Patch, and Transformers are gone. But if you've ever stepped on one of those puppies while barefoot -- it makes you want to curse the great nation of Denmark from which they sprung.
Legos: really awesome toy...really unthinkably painful to step on.
