The On-Line Encyclopedia of Integer Sequences (or OEIS, oeis.org) is a free web site that contains information about a quarter of a million sequences, and is often called one of the most useful mathematical sites of the Web. I will discuss some of my favorite sequences, including Queens in Exile, the Red Dot problem and the van Eck, Zizka, Fredkin, etc. sequences. There will be music, movies, and a number of unsolved problems.

**Warning:** some of these may prevent you sleeping at night.
