Abed tells Troy that the best part of his day are the 10 seconds from the time he sits down in Spanish class to the time he looks at Troy's desk, because he thinks maybe he'll look and Troy won't be there.
Troy's plotline in this episode spoofs that of "Good Will Hunting"; he shows a particular skill at plumbing and fixing pipes and is encouraged by Abed (spoofing Ben Affleck) and the janitorial staff (spoofing Stellan Skarsgaard playing Gerry) to pursue it.
