One of my Christmas presents was an Electronic Rock Guitar Shirt from ThinkGeek. It's a t-shirt with an electric guitar on it that you can actually play. Turn on the included mini-amplifier, turn it up to 11 (yes, it really goes to 11), then press on parts of the guitar neck with one finger while strumming with the included magnetic pick, and the shirt belts out power chords recorded from a real hard rock guitar.
(The one problem: strumming with no fingering plays an open E, which means if your finger misses, you don't get nothing, you get a very wrong chord. This is far too easy to do. It'd be better if an open strum did nothing so you could be sure what you play will sound like what you want to play. I know this shirt is never going to be played on stage at Madison Square Garden or anything, but it's a bummer trying to show it off only to hit a desperately-wrong chord.)
To my surprise, not only does the guitar-shirt not come with any suggestions for songs you can play on it (despite the claim that its limited range can play many real songs), I can't find any lists of songs people have played with theirs, on ThinkGeek's site or on the web in general. If such a site exists, Google doesn't even know about it.
So I'm going to collect them here. Hopefully this title will jump out at people on Google. If anyone reads this and has any they know, post them here and I'll add them to this page. As of this writing, I've only had time to play with it a little so I only figured out one song-bit which works, the intro riff to Smoke On The Water, but it works brilliantly, sounds very authentic. I bet there are a lot of others I just haven't had time to figure out.
Smoke On The Water intro riff: A C D, A C D# D, A C D, C A
Communication Breakdown intro riff: open E (x9), D A D; the entire rest of the song is these three chords
Rock You Like A Hurricane intro riff: EEE, CC, AA, C, DD, repeat
I Love Rock And Roll intro: EE EE G AA BB G EE (thanks to Sarah Antonelli for that one)
Crazy Train (not yet tested): F#F# AA EE F#F# DD EE F#F# C# F# D F# C# F# B A G# A B A G# E
