Here’s some late night fun from the folks at /.
“According to this article on Secunia, a new IE exploit was found that crashes almost any version of Internet Explorer past 4.0 with just 5 lines of plain HTML code (no JavaScript, ActiveX, etc.). If you’re very brave, you can test/crash your IE by going here.” There’s also a note on SecurityFocus.
What I want to know is who figured this one out?

Yup. Crashes every time.
