No, it's not something you see every day.
Something more impressive, IMHO, is Smiling Shard. 3x3 to mare Blue Horizion (dam of damsire Panorama and also dam of Smile Upon, who is sire Grinfromeartoear's dam).
I am testing some female family inbreeding (hopefully, if she gets in foal) with one of the mares this season. No star, just seeing if something comes out of it
