But for me any time I think of that song I end up thinking of one of my mom's favorite things to do during the Summers and it happened at least once a year until I was about 15...

We'd catch a bunch of lightning bugs and then she'd put them in the toilet and put saran wrap over the bowl and they'd light up and she'd sing "You light up my toilet" at the top of her lungs...she really got a kick out of herself when she did that...
