Transcript for Scouting All in the Family in Merit Badge Match
Finally tonight, as one family sits down to give thanks tomorrow, they'll be toasting their 14-year-old boy scout son who has accomplished what few scouts have ever done. And it all started out as a competition of sorts to beat his father's record. Here's ABC's John donvan. ? Reporter: If josh Mccoy hadn't finally learned to play the bugle, we wouldn't be talking about him today. And he wouldn't have his picture in the newspaper. And that is all about these, his boy scout merit badges, of which he has earned a phenomenal number, a dad-beating number. Because his father, Tim, earned 82 as a scout. That was first part of it, of wanting to beat my dad. But after that, there was still some fun merit badges left to do and I hadn't gotten to them, so I wanted to keep going. Reporter: Josh has gone way past 82 to 135. Which is the most anybody can currently get. So many badges, his mother Darlene sewed a special sash so they would all fit. It's actually two sashes sewn together, because the boy scouts don't actually have a sash that holds every single merit badge. Reporter: Some of his acquired knowledge he could actually demonstrate for us. Tying knots, programming a robot and bugling, which took him a while to get right. It took me two years. To learn to play 15 songs. Reporter: And three years is how long it took him to get the whole 135. And guess what? Coming up next, his little brother Zack. Who is already at 102 badges and counting. John donvan, ABC news, Washington.
