When Umbridge comes home from work, she discovers that all the closets and bathrooms are filled with shaving cream. Naturally, she does have suspects.
Umbridge: Why is there shaving cream all over the place?!
Sidious: I do not know, Madame Umbridge.
Umbridge: It's possible that either Peeves, Potter, or Weasely could have done it!!
Sidious: That is very possible, and I bet Peeves did it.
Voldemort comes in and starts kissing his girlfriend, Umbridge, in front of Darth Sidious
Voldemort: Hello, my little sunshine. What is going on in here
Umbridge: Someone put shaving cream in all the bathrooms and closets!
Voldemort: When I find out who did this, sweetheart, they will be very sorry they did this.
Umbridge: You don't have to do this for me, sweetie. I can handle it myself.
Voldemort: Of course. I don't have to, but I like doing thing for you. Please.
Umbridge: All right, you can do that for me, but please take Darth Sidious with you because you two are very powerful together.
Voldemort and Sidious: Ok.
