I am shamelessly crossposting from my big brother thread. Even though this is just audio (she is not seen on the toilet) I still think it deserves a post.
Nikki Graham from Big Brother Canada 4 is in the bathroom and at the 26:15 mark goes to the toilet, the only privacy being a curtain. We can then hear a strong stream for about 15 seconds before production unfortunately mutes the audio for around 10 seconds. The audio then comes back on for the last 5 seconds or so of her pee for a total of approximately 30-35 seconds.
