Caddyshack - At the mini golf course, Jorgen bounces on a pogo stick and shouts "I'm alright, nobody worry about me!". These are the opening words to the Kenny Loggins song "I'm alright" made for the movie "Caddyshack" which is set on a golf course.

Super Toilet from the episode "Super Bike" is mentioned in this episode. Cosmo also says the same quote "So much clogging!".
Characters mentioning or referencing rice.
Wanda's eyes changes throughout the episode.
When the “17 holes later” timecard appears, it is wrong. This is because since the miniature golf course has 18 holes, when Timmy and HP clear Hole 1, it is impossible for them to play Hole 19 after clearing the next 17 holes. It should be when they reach Hole 18, they should have been cleared the next 16 holes after clearing Hole 1 in this course.
