It is perfectly normal, that's the way our brain works with associations. The persistence of the theme is a bit obsessive but not in a clinical sense if it doesn't induce anxiety and a compulsive repetitive reaction struggling to fight the original thought or mental image. I don't remember the tune by the way.
I sometimes get 'the Inspector Gadget' theme pop into my head in these instances,Sometimes the A-Team build-montage music.Mostly, though... nothing.
I like to hum the indiana Jones one
Is this akin to humming the smurfing Hamster song for a full week straight at work? If it is, I want no part of it!
Yes, this one. Yes, I have the volume muted...because I don't want to go for another freaking week humming that evil tune.
so all this talk of macgyver and me listening to the link to the credits had me looking on netflix . . . watched the pilot last night with my kids (a *loooong* time for me, 1st for them) . . . they were not as impressed as i was one even decided he was going to bed - seriously, stay up late watching macgyver or bed where have i gone wrong ?
