It's a lo-fi alt-rock gem that sets the tone for the album. Another favourite is Continental Breakfast, which has Vile in full J Mascis mode, as the pair relate food to a long-distance friendship over a laconic feel-good strum.
It's not the only food-based song, the countrified harmonica-filled, yee-ha, whistling ditty Blue Cheese, calls to mind the novelty of fellow lo-fi duo Ween.
The Barnett-led Fear is Like a Forest ramps the energy up, slightly, building up to a cutting guitar solo and a catchy do-do-doo refrain, before Vile's rambling alt-country Outta the Woodwork - a cover of Barnett's Out of the Woodwork - slows things back down.
Barnett also takes on a Vile hit, reimagining his Peeping Tom as a solo acoustic number. It's terrific, but it's the hypnotically droning stoner groove of On Script that proves to be the album's highlight.
The record has an endearingly loose vibe to it, sounding very much like two pals having an easy jam on the porch. It's not a party-starter by any stretch, but it's easy to see Lotta Sea Lice becoming the soundtrack for both, casual afternoon drinks in the sun and the following dusty morning.
