The subreddit /r/Showerthoughts is full of brilliant, concise insights thought up in that great, steamy thinktank: the shower. We (most of us) bathe in quiet solitude, with neither friends nor social media to entertain us lest we get our devices wet and ruin them. Amidst all that lathering and rinsing, the mind wanders, and for the duration of each shower, anything is possible.

What do you think about during your most vulnerable moments? Space travel? The strange ways we use language? How cats have whisker-eyebrows and nobody really talks about it? This list collects the best of the Shower Thoughts subreddit – with credit to their original thinkers – for you to enjoy, ponder, and rank. Vote up the ones that make you be like, "Yeah. Yep."
