Plot hole: When everyone is eating dinner with Max, Sam says "would you like some Parmesan cheese?" Max then puts some on his spaghetti and says "it's not cheese, its garlic." Sam's mom takes the bowl and smells it to check. Considering it's minced garlic, everyone at the table would've smelled it! I realize Max and the boys knew it was garlic but the mother did not know this and wouldn't have had to put it right under her nose to smell it.
