Jim notices Dwight and Gabe in the break room posturing over who is more fit. Dwight displays his biceps, while a scornful Gabe talks about his killer core.

They duke it out while Pam takes pictures - which she and Jim eventually decorate and share with the caption "Sleep Over Party! We Gossiped All Night!"
