Continuity mistake: When Ben and Matt are sitting at the construction site drinking a beer, Ben takes a sip of his beer with his right hand in a close up. The next shot shows him holding the beer in his left hand, flicking a cigarette with his right. (01:43:55)

Visible crew/equipment: When Chuckie and his friends show to Will his new car towards the end of the movie, a boom microphone is reflected on the rear window and also on the rearview mirror's steel cladding moving backwards when Matt Damon steps on forward.
Answer: There are two versions of the joke actually. The original which is found on the DVD and then the made for TV joke. I don't remember how that one goes and it doesn't seem to appear on the DVD I've got, but the original joke is: All right, there's an old couple in bed, Mary and Paddie. They wake up on the morning of their 50th anniversary. Mary looks over and gazes adoringly at Paddie. She's like, "Oh, Jesus, Paddie. You're such a good-looking feller. I love ya. I want to give ya a little present. Anything your little heart desires, I'm goin' to give it to ya. What would you like?" Paddie's like, "Oh, gee, Mary. That's a very sweet offer. Now, in 50 years, there's one thing that's been missing, and, uh, I would like you to give me a blow job. I would like for it." Mary's like, "All right." She takes her teeth out, puts 'em in the glass. She gives him a blow job. Afterwards, Paddie's like, "yeah, geez, now that's what I've been missin'. That was the most beautiful, earth-shattering thing ever! Beautiful, Mary! I love ya! Is there anything that I can do for you?" Mary looks up to him and she goes, [Skylar takes a swig of her drink] "Give us a kiss." [And her drink comes out of her mouth, indicating what would be coming out of Mary's mouth in the joke].

Even funnier is she has to have a Guinness or a stout so what comes out of her mouth is really dark.
