Senior Discount was such a great episode! I loved how members of Mr. Krabs' and Old Man Jenkins' family constantly appeared towards the end. Mr. Krabs trying to make Old Man Jenkins leave in various ways was pretty hilarious.
As for Broken Alarm, I think it deserves a spot in my Top 10 favorite SpongeBob episodes. The visuals, jokes and pretty much everything about it were on point! Broken Alarm was a masterpiece.
