Other horrible puns that could apply to Sierra games are "you can finish this game at your LEISURE" (for LSL), "you won't be A-RESTING when playing this!" (for PQ), "play this and you'll be SPACED out" (for SQ), or simply "Knighty-Knight!" (for GK).
Go ahead and share your favourite groan-worthy puns!
Thanks for the compliment on the "Royal" pun. 
When we were setting up the forums, I just wanted to put some fun descriptions in here. Collector has decided to keep most of them! (I did the same thing over at my LSL forum - linky in the sig). As for coming up with more puns - I could probably come up with lists - mostly because I am a punny - that is, funny - guy!
