Ladies what should I do! Help me have a great weekend?

Where I work we have casual Fridays. Most people don't, and dress in suits, skirts and heels as usual. Last Thursday my friend Julie said wouldn't it be funny if someone wore their pjs and slippers one Friday. I said what’s the big deal? One of the guys i work over heard and started to laugh. He said that I would never wear my pjs and slippers to work. I said I would too. He said i bet you whatever you want you wouldn't do it. I accepted and the terms were if I did, he would be my maid/servant/spa boy. He would come to my house Friday night and that’s when it would start. I would have a bell to ensure I stayed comfortable. He agreed on the terms. Friday came I wore my matching heart flannel pj pants and top with my pink fuzzy slippers. It was quite embarring so I want my revenge. Any ideas? Please list what you would make him do if you were in my situation? We are in our late 20's and both single. Please no dressing him up, and no leaving the house.Just him pampering me ha! Thanks!
