From the "Terror in the Skies, Again?" article:
..."The man was gone for a very long time. And when he came back, he reeked of chemicals -- the chemicals from the toilet bowl. He absolutely reeked of it. And I thought, what was he doing in the toilet? He didn't smell like chemicals when he got up to go to the bathroom -- it was when he came back. It was so spooky. What was he doing in there? That he would smell so strong of chemicals from the toilet?"...
What on earth could he have been doing?
Bathing in toilet water doesn't sound very hallal to me.
