I taught myself PC-LISP when I was 12 years old, because I couldn't figure out how to re-implement ELIZA in BASIC. But everyone seemed to be saying that Lisp was a dying language, and I was young and naive enough to believe them, so I gave up for a while and learned a little C++ and a lot of Java.
Lisp isn't dead at all. I've been paid to write Lisp software. I know Scheme reasonably well, but Common Lisp is now my language of choice. The most amusing thing I've done so far in Lisp was to embed a Scheme interpreter in the Linux kernel (Schemix).

I also wrote, and currently maintain, LispDoc - a searchable interface to a bunch of Common Lisp documentation.
