Yoga - discuss!

Well I have been a little puzzled of late and I was hoping that some kind hoomun would be able to, perhaps, enlighten me a little on a few hoomun technicalities. You see, in the village there has been much excitement caused by a large poster on the village notice board advertising 'Yoga'. I have to report that I have absolutely no idea what 'Yoga' is. I once had a little infection in the little boys department and The Owner spent an hour chasing me around the gardens with a pot of natural yoghurt with a particularly menacing look in his eye but I don't think that is 'yoga' and anyway he soon gave that up and went back to his Sunday papers. The air of excitement throughout the village was palpable as the day approached and then one night in the week The Owner put me and Barney K9 in the back of the car and off we went in the general direction of the village hall. Barney K9 and I were left outside under the tree which was pleasant enough for a warm late summer evening except the one hour turned into several and me and Barney K9 were still sat under the tree, and it was, by now, quite dark. We were curled up asleep as it was also quite cold by now when I heard the dulcet tones of The Owner singing coming from the general direction of the pub. How did he get past us and up there???? And what does it have to do with 'Yoga'. It was a long walk home that night as he insisted on singing (badly) and then periodically stopping and pulling a funny face and going "Oohhhhhhmmmmmmmmmm!" very loudly. I don't understand why?? Once home and Barney K9 and I were fed The Owner sat down and poured himself a large glass of something red. He said to no-one in particular that as he felt the benefits of 'Yoga' already (surely that was just the effects of four pints of 6X?) he was going to do it every night for an hour when we got home. The following evening we returned home and me and Barney K9 were fed and The Owner poured himself a large glass of wine and flopped down into his armchair. He said his first "Oohhhmmmmm". Only it was cut short when he fell asleep in the armchair. After about ten minutes the snoring started, he was properly asleep now and as his hand relaxed a little, the wine glass that was still full of "A particularly good vintage" fell out of his grasp and deposited its contents over his lap. The Owner bellowed loudly and Barney K9 made his excuses and went to bed to get out of the way, quickly. The opened bottle was the next victim, as was his new settee, delivered that week, as the bottle deposited its contents down the side of the cushions. He spent the next hour looking crestfallen as he mopped up the mess. I couldn't help but notice that his "ohmmmm" ing was a little less enthusiastic now. In fact it was no-existent to be truthful. So my question is to anyone who can offer any help..... Is this what Yoga is really about?
