Well not me personally, but I was there to witness the account.
Fellow user Myt332 and I (I was spectating actually) were cleaning out his tropical fish the night before we flew to Cuba. He had to rip off the dead leaves from the plant that they had in there, so he was there filling up a container with all these dead leaves, instead of putting them with the garden waste or in the bin, he flushed them down the toilet!!
I have never laughed so much in my life! He was there with a plunger forcing them down! If only I had taken some shots!
