I do not mind teaching the same courses. I find that I challenge myself to find unique ways to deliver the information and see which deliveries work best for student interest and student retention. Students seem to really enjoy the clinical experiences that I bring to the classroom.
Some fun learning moments include:
using pop rocks for sensory learning,
using glitter on my hands and shake everyone's hand as they enter the classroom therefore sharing the glitter "pathogens"
making a huge heart with 6 pieces of poster board and having the students walk through as a blood cell.
