I See What You Did There
Published August 30, 2026
"I See What You Did There," often shortened to ICWYDT or ISWYDT, is a sarcastic online reply used to call out a pun, an attempted joke, or a moment of hidden cleverness. The phrase jumped from a 1996 Friends episode to early 2000s forums, then grew into image macros and a widely used rage comic face by 2011.
Overview
"I See What You Did There" works as a compact reply for calling out another poster's cleverness. Tone shifts the meaning: it can read as genuine appreciation of a good pun, a condescending eye-roll at a weak joke, or a hint at noticing something sneaky. Urban Dictionary describes it as "obvious sarcasm" used to point out that a previous post was not as funny as its author thought1. The acronym forms ICWYDT and ISWYDT function as shorthand for the same reply1.
By 2011, the caption was paired with a specific sideways-glance reaction face that had been circulating on 4chan since February that year2. Rage comics using the face turned the phrase into a stock reaction for wordplay, hidden references, and characters catching on to something they were not supposed to notice.

How to Use This Meme
The format typically pairs the phrase (or its abbreviated ICWYDT / ISWYDT form) with the sideways-glance rage comic face or an image of someone giving a knowing look. Users often reply with it under a pun, a hidden double meaning, or a comment that thinks it's cleverer than it is. Tone flips with context: appreciative for a solid joke, sarcastic for a groaner, mildly menacing when calling out something someone tried to slip past.
