Let's face it - Sierra's games are amusing.
The Larry games are an obvious candidate here. (Of course, I'm not counting such abominations as the Larry Lovage games). The ad-libbing by Hans, Franz and Ivan is hilarious.
I know a lot of people think Punny Bones and Gnome Ann are annoying, but I thought they were rather cute (in a slightly annoying way).
The voice acting in QfG4 is wonderful... really gives the characters personality. Same with the GK games. (Speaking of which, the narrator in GK1 is sometimes unexpectedly funny, even when she doesn't mean to be).
Space Quest is also hilarious, particularly the death messages in SQ1, 2 and 3 (although they're also obviously annoying!)
I don't know if anyone here played Sierra's card games/board games, peopled by characters from the Sierra games? This is going back a bit (something like the late 80s/early 90s)... you could play card games or board games with Larry, King Graham, Roger Wilco, Sonny Bonds et al., and they'd make wise-guy remarks (if they win or you're taking too long over your move) or ask for commiserations (if they lose). The games are definitely meant for kids, but I liked them.
Also - not sure if anyone ever played an old Sierra game called "Jones in the Fast Lane". If you haven't, it's a fun (and funny!) little game to play. Try it out - you might like it.
Anyway, I've been going on for far too long... what about you?
