I do, in the morning. I just kinda sing songs I know, even if they suck shit. I don't do it Ferris Bueller style and use a pretend microphone because I just do it without really knowing. It's really out of control.
One time in high school, I showered in my dad's bathroom and I was up early for football practice and I ended up shouting Biggie Smalls. I was really on a roll, I think I went through 2 songs before my dad told be to shut the fuck up.
In college I smoked Warlock Robustos by the dozens at the same time, making me a great Rat Pack impersonator, until I realized that that was an awful combination once I started showering with my girlfriend, or whatever girl I had picked up the night before
So what about you NG?
Side Note: I don't want to know if you jerk off in the shower, I'm telling you this in advance
