...oh, c'mon! You know you've done it -- You feel one coming on and you lean back, open your knees a little bit, and just wait for those bubbles to come percolating up from under your butt. And, you enjoy the feeling of the fart passing out between you and the porcelein goodness of the tub, forcing you to rise up just a little bit to let it go. In fact, if you could, you'd probably eat a can of beans right before taking a bath, just so you could enjoy that glorious feeling! It's like your own personal jacuzzi! See, this is why showers suck -- No fart bubbles!
