I was thinking back about cool tradeshow swag. One year I got a Dilbert tee shirt. Another I brought home an R/C dirigible. We still use two letter openers I got at shows in the 80s (I think Sun Microsystems and Fuji storage). I got soe really cool mugs at shows. The craziest thing was at a show in the early 90s while I was with Pencom; two of us were sent to a party in the hotel suite of a competitor (owned by a couple of sleazy ex-Pencommies). They had nearly nude booth bimbos plying the men with drinks and trying to rub up against everyone, complete with suggestions there could be more offered if we did business with the company.[1][2] They insisted we each take a somewhat bulky, somewhat ugly keychain with us as we left. It turned out to have a secret compartment with a (still packaged) c0nd0m. Yeah, seriously.
[1] The Chick Magnet[tm] had his magnets set to REPULSE. He still had to do some dodging.
[2] I have no idea how serious they were, but given the stories about the owners, it might well have been true, depending on what the company would get from it. The name of that company was flushed from my mind long ago. I just think of it as Sleazy Ex-Pencommies.
