Here is a variation on a recent one I did.

Jake, Norm and Grace are locked up in the brig. The guard comes in with the dinner trolly followed by Trudy.

Trudy: These traitors get steak.
Guard: Yeah. Incredible isn't it.
Trudy: I tell you what. If you pretend that I have hit you over the head and freed the prisoners, perhaps we can have some fun while they eat their steak.

After serving the prisoners the steak, Trudy and the guard disappear into the other cell.

As they are eating their lunch, the three prisoners hear sounds of rough love making which end with some loud ecstatic moans from Trudy.

Trudy opens the cell door and lets the three prisoners out.

Norm: What the hell were you doing?
Trudy: I had an orgasm and freed you just like you told me.
Norm: But I told you to come and rescue us.
Trudy: Exactly.

Grace and Norm are taking readings on the forest floor.

Grace: Do you see it?
Norm: It's amazing!
Grace: Isn't it.
Norm: It's more than amazing. It's ridiculously outstanding!!!
Grace: Yes. It's great isn't?
Norm: It's absolutely awesome. It's so thrilling. I'm so excited. I can't contain myself.
Grace: Er right, Norm. I think you should calm down now.
Norm: Oh, my God. I think this is the greatest moment of my life.....!
Grace: OK, Norm. Control yourself....! And put that thing away!
Norm: I can't help myself. I' just going to explode......HELL YEAH!!!
Grace: Oh, Norm. You've just contaminated the sample with your semen.
