Anytime I see flip-flops I think of cold beer and large bodies of water (ocean, lake, pool, slip ‘n slide). I’m sure that’s not exactly the imagery those people are trying to elicit.
UPDATE: I was looking at that site after I had posted this, and one of the pictures drew my attention and prompted this little update. Take a look at the picture with the caption, “In the locker room, these young Christian men protect their feet and leave the greatest impression.” Doesn’t the guy on the far right, the one wearing the Nike hat, look stoned out of his ever-lovin’ mind? Seriously, he looks like he’s propped up on the wall. Nice Christian image, that guy.
