Barenaked Ladies - Same Thing lyrics

What does it mean to wake out of dream and Be wearing someone else's shorts? I've been around the block, at least on my bike I was prepared for the news but not for a full-scale war Found me an answer, In a grocery store Found me an answer in the form of an old man with a cardigan on This guys got thirty years on me but he stops and smiles Just to say "Hello - didn't I see you on TV?" Must've been the same thing Must've been the same thing Must've been the same thing Charlie Brown went through I'm in a comic store Looking for some mistakenly-priced comic I could make a fortune off In walks the Fantastic Four, I say "Don't go - that last issue was cool." Must've been the same thing Must've been the same thing Must've been the same Same thing These things all end Who asked you anyway? You have to bend Who asked you anyway? I'm in a thunderstorm Staying out from under trees, never holding golf clubs But still seem to be getting struck by lightning Must be something in my veins My weathered veins Must've been the same thing
