The one that i recall being told by many of them is when there was a get-together at my house, with special guest Lopon Tsechu and Lama Kalsang as a translator. Visualize about 15 people crammed into our small living room, about 7x4 meters of area (this was inside an apartment.) Outside, one of our sangha friends wanted to bring yet another person. My dad went more or less angry since we were far too many inside the room and this guy wasn't invited and wasn't part of the local sangha, just an outsider interested in buddhism who wanted to meet the famous Lopon Tsechu.
After some arguing, my dad agreed and this guy was allowed into the apartment. After he entered the door, Lopon Tsechu suddenly stopped doing what he was doing, and gestured the guy to approach to him. The guy sat besides Lopon Tsechu. They observed that he and Tsechu Rimpoche went talking for a quite long time, and that Tsechu started putting his finger on the top of the guy's head, in the typical point of the head that is signaled on a phowa (conciousness transference at the time of dying) retreat.
The rest of the people -the local sangha- were amazed at how this stranger just entered the door and then Rimpoche, without asking, stopped caring for the rest of them and just basically devoted most of the evening to him... I would bet they were a little bit jealous.
About seven days later, the guy died on a traffic accident.
