The super catchy piccolo bass riff on "Jerry Was a Race Car Driver", especially after it appeared on the Tony Hawk Pro Skater soundtrack.
The deep repeating double bass note that opens Primus and the Chocolate Factory's overture piece, "Hello Wonkites".
"Shake Hands with Beef", combining a driving, drilling bass riff with ominous lyrics and a shuffling beat to make a song that's both eerie and catchy at the same time.
"Wynona's Big Brown Beaver", a wacky half-innuendo half-jokey song about a woman named Wynona's (literal pet!) big brown beaver.
The slow boil of "Southbound Pachyderm".
"Tommy the Cat", with special guest Tom Waits! Waits' charismatic storytelling Motor Mouth is backed by some of the best instrumental performances the band has to offer, and it's a golden combination.
With its measured, harrowing instrumentation, equally sobering lyrics and unsettling vocal deliveries from Martina Topley-Bird, Waits and of course Les, "Coattails of a Dead Man" off Antipop is a sterling gem.
The mostly muted slap bass riff and perfectly timed drumming of "My Name is Mud".
