Regardless of whether you scrunch or fold your toilet paper, you will have all experienced a one wipe wonder! You know, you’ve done a no.2, had a good wipe and when you look there is no mark on the toilet paper. This is sometimes known as an ‘Angel poo’.
However, in practice, angel poos never are just one wipe as although there is no mark we cannot trust it. We need to have another wipe just to be sure. So even the most angelic of defecations will require the minimum of two wipes.
