How has Hot Fuzz not been brought up? Officer Danny at seeing the vast storehouse of weapons lets out the best line of a shocked "By the Power of Grayskull!"
And of course Stewroids episode of Family guy after Stewie bulked up and lifted the weights crying I Have The Power! and the inbetween He man prompt splitting the scenes.
Tons of others i am sure but those were the 2 off the top of my head.
Well and Robot Chicken of course ;)
