DIP packages & the 555

My favorite story about the 555 has nothing to do with its function, but rather its form. I was working at an electronics store and a customer came in with a desperate need for a 555 (a radio station was off the air until the part was replaced in some critical circuit that should probably have been redundant in the first place). I fetched our *last* 555 from the warehouse and noted that, in addition to the four legs coming out of each side, there was one coming out the end! Of course, the jokes immediately started about the male version of the chip, and we were actually reluctant to sell our 'breeding stock' 555 and speculated on how it had escaped from the 555 ranch. But alas, the customer really REALLY needed the part, and off it went.... I've never seen another like it - although to be honest, I haven't expended much (any) energy in looking for one.
