Interesting stuff. Just thought I'd point out - you say "piqued SPOnG's interest," not "peaked" :)
Yes, we did say that - and I've now changed it.
Pique - "to excite (interest, curiosity, etc.)"
Peak - loads of definitions, from peaked cap to looking ill to being at the point of maximum frequency.
Although 'peaked my interest' has become common usage, it's lazy and sloppy and I have shot the sub-editor responsible in the head with bullets made from his own teeth.
