The author began collecting sequences in 1965. Today the On-Line Encyclopedia of Integer Sequences (www.research.att.com/~njas/sequences/) contains over 67,000 sequences and gets over 17,000 hits a day. It has been called a "fingerprint service" for number sequences. I will tell stories about some of the most interesting sequences in the collection. Many unsolved problems will be mentioned.
