The "Last Thing" Game

[zort]

This game is like "First Thing" (commonly known as Word Association), but you must say a word that has nothing to do with the previous word. To encourage adherence, you must explain why your word has nothing to do with the previous word. The explanation doesn't have to be long; one brief sentence is fine.
I'll do the first three to kick things off.

Sex.

Sky. This has nothing to do with sex because one is a biological activity and the other is, you know, a region defined relative to an observer on the ground.

Book. This is a small information-rich object, which has nothing to do with that big blue area outside.

[A-Man]

Light. This is a particle/wave with energy, which has nothing to do with the information-rich object.

Small Penises - Higher vertebrate male containing self-conscious thoughts about the length of their genital organ. The vertebrate must carry the duct for the transfer of sperm and the elimination of urine but is also the reason as to why their species develop the need to compensate for their lack of genital size and become over achievers. This information you're reading does not pertain to light in any shape, way or form as may have been addressed by the user above.

WTF - An abbreviation for an inappropriate statement which is often used for a surprising expression from the writer. And obviously, WTF doesn't relate to small penises at all. And can we please keep profanity stuff away from here.

Irony - incongruity between the actual result of a sequence of events and the normal or expected result. Example: Saying WTF, and then wanting to keep profanity away from here.

March 2008 is a date sh*t
anyways 2+2=5 there is no confusion here, it's just as you see it.
And there is no irony behind math (at least i hope not)

[zort]

Fountain. I can't think of a connection between an incorrect mathematical statement and a water-spewing thingy.

Hark! I believe I see reasonable connections going from the words "sky" all the way through to "WTF":
sky -> book: light is used to read books, and light (not all of it, but much of it) comes from the sky
book -> light: again, light is used to read books
light -> small penises: small penises are lighter than the typical penis
small penises -> WTF: penises are used for f***ing (censorship not mine)

Let's carry on, though.

Ant: because i can.
