My girlfriend and I tend to get quite vocal when the machines decide to send the ball SDTM. Standing outside you can hear me plain as day. I'm sure the neighbors next door think that the ol lady and myself are trying to kill each other on a nightly basis.
We do not hit the machines though... I'm with VT8Man, it hurts too much! I tried a bang back once on my TZ and my wrist was throbbing for an hour. served me right I guess. lol
