I belong to an academic society for Pentecostal studies. I make memes for the members of my interest group to encourage them to submit ideas on papers they will write and then read at our annual meeting. The paper ideas are called "proposals". All my emails to them are humorous. This time I said I asked the Cookie Monster to encouragement for them to submit their proposals. But, he can't help talking about his favorite subject. Thus the joke. Now you get it. If you look on my page I have other memes that work towards the same goal.
