Shining some glory on me

We didn't expect to be forcibly subjected to Britney Spears. We didn't expect that guy to start stripping. We didn't expect him to create a large, modular, plastic mock phallus. We didn't expect him to employ the mock phallus in such a manner that would lead to what followed, and we didn't expect that products of his mock climax would shoot through the air at us.

Then again, I didn't expect everyone to start dancing to “Hey Ya”.
