QBASIC: I had a coding friend in elementary school and on the weekends we had QBASIC sleepovers. We stayed up til 3 or 4am making barely playable games and fake imitations of operating systems. I remember the vivid rush of excitement when something actually ran: almost unbeatable (only skydiving, burning man, camping, and some fun time spent naked have compared since).

Much more recently, learning OCaml after many years spent coding C++ was like a long drink of cool refreshing water.
