i was watching "Company Man" and i was wondering if....?

ok i was wondering if anyone remembers the năm of beethoven's đàn piano sonata that was refered to in "Company Man". from the episode i remember mozzie looked and the sheet âm nhạc in Diana's bag and i dident catch what it said. but later mozzie đã đưa ý kiến that it was beethoven's đàn piano sanata then he đã đưa ý kiến a năm and i cant remember what it was if anyone remember hoặc can find out the information would be greatly aprecated. if that was kinda confusing just tell me and i'll try to refrase it.
