The sentence "IT'S ALL OF THEM" can be considered funny or ironic in the context of several humorous or ironic paradigms. Humor often relies on the surprise or the unexpected, and this sentence ticks the box for both. On its own, it doesn't translate as something funny, but if used strategically in suitable scenarios, it can generate laughter. For instance, if someone has been methodically eliminating suspects or culprits in a mystery and concludes with a triumphant "It's just one person", the pronouncement "IT'S ALL OF THEM" in response from another participant can be seen as hilariously deflating their tactics.
Secondly, the humor could lie in the fantastical or implausible aspect of the claim. Taken literally, the phrase "IT'S ALL OF THEM" suggests a universal statement that includes everyone or everything within a defined group. The comedic element can stem from the improbable fact of universal involvement. For example, imagine someone frantically searching for a person who ate their last saved cookie and proclaiming "IT'S ALL OF THEM" humorously implicates everyone present as the thief.
Additionally, irony could arise from the sentence "IT'S ALL OF THEM" if it contradicts the speaker's previous assumptions or statements. Irony is based on the incongruity between what might be expected and what actually occurs. If the speaker had earlier assured with confidence that it was only a few or none at all, the revelation that it's everyone or all can have an ironic impact.
Furthermore, the terseness of the sentence can add to its comic timing. Comedy is often about delivering the punch line at exactly the right moment and the abruptness of "IT'S ALL OF THEM" can work perfectly for that. Therefore, if the context is right, this phrase could create an impactful and amusing comedic punchline.
The sentence "IT'S ALL OF THEM" may also be read as sarcastic, depending on the context. Sarcasm is a type of irony often used for comic purposes. For example, if this sentence is used to answer a question where the individual asking already knows the answer or where the answer is glaringly obvious, then it could be read as a sarcastic remark that makes people laugh.
Lastly, the sentence in all capital letters could also add to its humor. The usage of caps lock often signifies shouting or strong emphasis in textual communication. Thus, the severity of the statement contrasted with an otherwise casual, non-serious scenario can create an amusingly dramatic effect, making the sentence funny. ITS ALL OF THEM
