Mike: A vintage Action Cola can! Complete with contest rules and a worded disclaimer about how no one can win!
In "Flustering Footwear Flotsam", Margery begins making "shoe portraits" and desperately wants Mike's red shoe to finish a potrait of the island's founder.
Margery: Hello, Mike! Why don't you take off your shoe and stay awhile? Or not stay a while; just take off your shoe.
Mike in therapy with Queeks, stating that she's been wearing the same pair of shoes since she came to the island (and they're smelly enough to prove it).
Queeks: ACK!!! YOU KEEP YOURS ON!!!
The whole episode, really.
From "Whole Lotta Shakin'"
Mike worrying about the volcano erupting, admitting that she never saw a PG movie.
Followed shortly soon after by a Big "WHAT?!" when Lu tells her that the volcano's activity is a time for celebration rather than fear.
In "Thanks, But No Thanks", Margery is cooking something that requires her wearing a welding helmet and eventually a radiation protection suit. Talk about Lethal Chef.
From "A Boy's Game":
"WHO'S DA GIRL! WHO'S DA GIIIIIRL!!!"
While playing his extremely difficult handheld game, Og states he was so close. The camera pans out to reveal that he's on the edge of a cliff, during which Og finishes his sentence by specifying that he was close to falling onto some jagged rocks.
In "The Three Amigas", Lu sees the newly-befriended Mike and Hermione wearing "nose bones". Lu shows up with a bone through her nose too in order to fit in. However, Mike and Hermione reveal that their bones are actually clip-ons. Lu on the other hand...
Lu: Does it hurt?
In "The Great Snipe Hunt", Margery is cooking a "pea cake" for Og's birthday. Mike questions that it should be a carrot cake. Margery's response?
In "A Learning Experience", Mike gets ready for her first day of school on the island.
Alfred: Are you ready for school, Mike? Mike: Yep. I've got pencils, a backpack, and a new protractor. Alfred: That's nice, dear. But, are you ready for school?
That joke then makes sense about a minute later, when we find out what exactly is school there.
Plus, when Og points out a "school crossing" on their way to school, Mike scoffs at the idea, saying there's nothing to watch out for. Once she steps onto the crossing, a stampede of elephants rushes by.
Mike:Safety first. (pan down to reveal her foot sticking out of her torn shoe)
