Legos haven't become astronomically expensive in the past 35 years — a new international study says the popular kids' toy has also developed a bit of an attitude problem.
Lego characters released since the early 1990s are proportionately more angry, the study found. Authors of the study hypothesized that the spike in negativity could be related to the release of more thematic Lego sets — such as pirates or "Harry Potter" — that include weapons, along with miniature figurines representing "good guys" and "bad guys."
