I have actually done it.
Everyone knows that muslims have to take their shoes off when praying. Well, the women sit on one side, while the men sit on another.
I dressed as a woman and put on make up and all of that jazz and went to a masjid (holy heresy Journia! What did you do next?) I sat down and in the middle of the khutbah,the sermon, I began to poke the feet of a girl in front of me. ever so lightly, she began giggling during the sermon, and turned around to see who it was, of course I had taken my hand away, and I had it at an awkward angle in case just such a situation arose. I continued until some woman spotted me and called me out to the imam, priest.
