Great episode, the seaosn ended on a good note.
Best gags were HOmer naked, the balls, SLH with the homework, Ned with the tumbleweed, Homer saying his doctor said no walking when it was a traffic signal, MAggie with the Jack-in-a-box, rod & Tdd sewing & ironing BArt's clothes & HOmer saying you can find out who shot Burns.
Also, nice callbacks to "My Big Fat Geek Wedding" & "The Seemingly Never Ending Story" wsith them showing CBG & Moe dated Edna.
