Funny / Stalker (1979)

• Early on, the Writer idly sets his hat on top of a car, and tries to convince the Stalker to let him bring an attractive woman he's clearly trying to impress. After the Stalker chases her off, the car drives off with his hat, which clearly distresses him.
• Professor decides to go back for his rucksack. Stalker tells him numerous times that he's likely going to get lost and/or die, but the Professor insists and just buggers off. Stalker and Writer worry almost the entire trek through an unnatural waterfall in an arduous and lengthy sequence as they both hope there aren't any anomalies... and find Professor sitting on a rock, enjoying coffee and sandwiches, asking why they look so tired.
• The dry tunnel is not actually a dry tunnel.
• When they enter a room with a phone inside, and Writer begins another one of his rants at Stalker, the phone begins to ring. After ignoring it for a while, the Writer finally picks it up, and after a moment of short silence, he replies "No, this isn't a clinic.", before hanging up. When he resumes his rant, he suddenly stops and looks with Stalker and Professor at the phone again, realizing that the phone he just used is functional. Professor then decides to use it himself to yell at his boss.
• Before entering a dark creepy tunnel, and after losing to Stalker when deciding who should go first, the Writer asks Stalker to throw a bolt inside. The Stalker agrees, but, instead of a bolt, he throws a big rock in there.
