Since June 17 is Father's Day, why not give your dad a big surprise? Make him King for a day. Have a program in his honor where you host and perform while your mom will be the audience along with your dad who will be seated on his thrown.
Get his favorite chair, cover it with some silky stuff (a bed cover will do) for his throne, make a crown out of cartolina, then color it and a scepter too using rolled cartolina, paint it of course and a sash bearing the title "Best Dad in the World". Prepare the whole thing before he comes home from work. Then when it is almost time for him to arrive, you might want to switch off the lights and when he steps into the door, switch on the lights and tadaaaa, let the program start.
