I don't know if they showed it last night (I doubt they did) because the first time the episode aired, the showed the "How'd they do that?" a night later.

EMHE gave the Higgins' kids parents a proper gravesite and marker. Being that their mom and dad died only a short time after each other, and given the kids' inability to give them the proper funeral, the parents vever really gave their parents the kind of funeral they deserved. While on vacation, Ty and the crew laid beautiful stone markers for their mom and dad, and this brought the entire Higgins-Leomiti clan (and I'm sure audiences too) to tears. It was truly a touching moment.
