Funny / The Secret Life of Walter Mitty

• Walter's "Benjamin Button" daydream.
• The "Ted vs. Walter" daydream, due to how hilariously over-the-top things suddenly get, with the two of them suddenly possessing Super-Strength and relentlessly chasing each other through the streets of New York over a Stretch Armstrong doll.
• On another daydream-related note, there's the brief one where after Ted asks Walter what his job his, and when he initially struggles to answer him and Ted tells him he already tuned out, he comes back with a pretty good jab at Ted's beard:
  Walter: I was saying you know who looks good in a beard? Dumbledore, not you.
  • As clever as the comeback is, it's his coworkers' insanely contagious laughter that makes an already funny scene that much more hilarious.
• How does Walter find the source of the picture of a man's thumb? He finds the man, a drunken helicopter pilot singing karaoke, in the first local bar he enters and gets in a drunken fight with him. He notices the ring on the man's thumb fast enough to not get shanked with a broken glass.
  Walter: I just can't believe I actually found your thumb.
  Pilot: There's like...eight people in Greenland.
• Walter having to outrun "six horny Chileans who want to go to a strip club" to get to the only form of transportation on the island: A bike.
  • Even funnier is that strip clubs are illegal in Iceland. Though that doesn't mean there aren't any obscure or hidden ones these guys know about.
• Then, after Walter breaks the bike and has to continue on foot, he encounters three boys in Iceland, one of them carrying a skateboard, which Walter is adept at using due to learning in his younger days. He gives up asking for directions, since he cannot understand them and they don't understand him, but manages to get across that he wishes to trade away his Stretch Armstrong toy (a gift from his childish sister) for the skateboard, which he can use as transportation and to give to his love interest's son as a gift. The boys discuss it amongst themselves but eventually agree. Why? Because they can use it to tie up one boy's sister.
• The scene of Walter getting attacked and detained at the airport, shown through the x-ray scanners.
  • Followed by the brief scene of him being questioned by airport security. Particularly his completely deadpan response when he mentions passing through Yemen and they tell him it's a dangerous area.
    Airport security officer: How did you get to Afghanistan? There's a travel ban.
    Walter: Through Yemen?
    Airport security officer: Violent place.
    Walter: That's why the airfare is only $84. Can I have my fife back?
• "...Okay, that's a shark."
  • Followed by the old man on the boat cheering Walter on and giving such helpful suggestions as "Poke out its eyes!"
    • His pronunciation of "porpoise" ("pore-powse") adds some humor to the situation.
  • During that same scene, we get this little gem when the captain is trying to inform Walter that he can't be in the subzero waters for long, but doesn't want to panic him:
    Tawler Captain: You have at least a minute before you freeze.
    Walter: [struggling to hear him] What?!
    Tawler Captain: ...You are safe.
• The Icelandic hotel owner confusing "eruption" for "erection" while trying to warn Walter of the volcano.
