These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Freud Was Right: Yes, Valkenheiser's artificial nose does look like a tip of a penis.
One-Scene Wonder: Digital Underground's appearance is the most popular scene in the movie. "Same Song" reappears during the end credits, "Tied the Knot" was used during the wedding sequence, and Aykroyd directed the music video for this song, which featured clips from this film projected at a drive-in.
Retroactive Recognition: You might notice Tupac Shakur as one of the Digital Underground's back-up singers (Tupac actually worked with Digital Underground before going solo, so it's not that big of a surprise if you know anything about Digital Underground or early 90s rap).
