OK if your going to go there then this should not be a surprise to you.
I was trying to cram my pipe down a hole and my buddy said "Stop. Try spitting on it first! - you need some lube!!!" After I got it all the way in I just smiled and him and we both went for a smoke! hahahah - So bad. The next time I just took off the rubber! OMG so bad. I am of course referring to installing an ACO shower drain over their rough in. The #$$%%^ is tight.
You don't hear that every day on the job site! LOL
