A virtual friend of mine tweets that the song "Poison" by Bell Biv DeVoe has commandeered his consciousness, and it sets about this weird cascade of music stuff for me.
Step 1: The songs instantly wows to life in my head, and there it's been ever since.
Step 2: I add it to my "Video of the Day" widget on my blog.
Step 3: I chuckle that the title of the video I'm replacing is "I Don't Feel So Well" (which would make sense if one were poisoned).
Step 4: I remember that the Muzak at our store has been repeatedly playing "Mr. Telephone Man" over the last couple weeks (and it's as stupid and insidious now as it was in 1984).
Step 5: When I want to ensure that "insidious" is precisely the word I want to use, the online definition gives me, "a subtle poison."
Step 6: The song in my head gets louder.
Thanks, Paul! That was actually kinda' fun.
