I originally wrote a critical review of this show but has since grown on me and I have raised it to a 7 (from a 5). It grows on you. This show is infrequently now on the cable channel Decades which is CBS's old catalog. They are showing short lived and forgotten shows at the 5-6AM time slot like Boston Blackie and Mack and Myer for Hire. As a nostalgia fan I like to watch TV shows I never heard of before at least to become familiar with them. I also think its available in the public domain at Internet Archive. I was born around the same time this was first aired but I don't recall ever watching it on NYC's TV in the 60s (although Wikipedia says it was shown there) and I watched a lot of TV, but in all likelyhood I did watch it but have no memories of it, its very light comedy designed for kids. So what do I think after watching this for the first time in 2020 as a middle aged adult who still loves watching The Abbott and Costello Show and Laurel and Hardy? I think it's a lot of the same humor without the adult themes of Abbott and Costello like with Abbott chain smoking and the boys not paying their bills and chasing after dates, and also lacks violence between the two no matter how much Myer hurts Mack like in L&H. Interesting that Myer wears a hat like Lou Costello and has similiar facial expressions, so I assume this is a kids version of that show. I read the bios of the two comedians and now recognize Mack was on Three's Company and it is interesting that Myer has connections to Phil Silvers, Sydney Fields and Abbott and Costello skits (and the 3 Stooges)! So I may watch some more if they are shown again on Decades. 7 of 10, its very light children's fare but not bad for adults either.
