In my playing days as a TH I used to prop my best mate at hooker, we'd played together for years so had an excellent understanding. He was a very good technical hooker and used to take LOTS of ball against the head, even on a lot of times when it was a crooked feed. His dad ALWAYS came to watch him and used to talk to the opposition spectators to get information about the teams we were playing. Some of it useful, mostly not. On this occasion it was. He overheard two alickadoos discussing the opposition hooker saying that having been dropped from the firsts he was out to make a point, he came running over to us to let us know this little tidbit.
At the first scrum my mate looked at me with a view to pincering the hooker. so we duly did... The ball came in, my mate had a flash and nearly took the ball against the head; he then piped up "F**K me... No wonder you were dropped." The other hooker stood up and started throwing punches, all of which missed. The ref blew up, started lecturing us and asked what had kicked it off, The opposition LH said, nodding in the direction of my friend, "He said, F**k me no wonder you were dropped, having seen him hooking I agree. He's gonna be lucky to be playing in the thirds next week".
Once the ref had stopped laughing he reset the scrum and told us not to be children.
