Knots Landing Puns

So my brother, my dad and I were working on my car a while back and while my brother was underneath the car my dad must've seen a dent in the side went over and grabbed a small 2x4 to get it out. I saw him with the wood and asked him what are you doing? His reply, "I'm just board". My brother's immediate response, "You should tell your wife about this but it might go against the grain". My direct follow up, " I don't know that joke might land it might knot."
