June 17 may be Father's Day, but all the handy moms of the world will be busy watching HGTV that evening. Tune in for a Mike Holmes prime-time marathon starting at 7PM EST. You can catch some episodes of Holmes on Homes and Holmes Inspection that you've probably already seen, but wouldn't mind watching again. Oh, OK...I guess all the handy dads of the world can watch too. It is their day, after all.
