Unbridled Puns

So, I'm a Spanish professor, and I gave a final exam this morning. One of the last parts was that students had to write a paragraph using reflexive verbs in which they describe their daily routine. Since the class only had nine students in it, I told them that if they wanted to wait, I would grade their exams for them and tell them their class grade.

It was an open-book final exam (11 pages long), so I was in my office, and a graduating senior finished first and gave me her exam. When I got to her paragraph, I saw that she had written in Spanish that every day she woke up, got up, took a shower, got dressed, brushed her teeth, ate breakfast, and then she and her friend Emmy went horseback riding. Now, I knew that she didn't go horseback riding, ever, but that it was vocabulary from the previous chapter. The following conversation ensued:

Me: Horseback riding? Really?
Her: Yep!
Me: Every day?
Her: Yep!
Me: Every single day?
Her: Sí, Señor.
Me: I guess you could call it a stable routine then.

Unbridled force.
