Dad sets you up to fail a lie test by making a funny face
Dialogue
Overview
This single-panel meme has two sections of text at the top, followed by a reaction image. The first text line reads: "Dad: look at me in the eye. If you laugh, you're lying." The second text line reads: "Also my dad when I look at him:". Below the text is a popular edited image of former US president Barack Obama's face morphed into the shape of a triangular prism, with a deadpan, inherently silly neutral expression. The joke is relatable to many people who have experienced parents setting a rule that you will be caught lying if you laugh, then intentionally making a ridiculous face that makes it impossible not to laugh, setting you up to fail the test on purpose.
Origin notes
This meme was shared on the Reddit r/Meme subreddit, as stated in the provided source information, with the original poster titling it "lmaooo ts so true". It repurposes the widely circulated "Obama Prism" (or Triangular Obama) meme template, a popular edited reaction image commonly used for deadpan, silly comedic contexts online.
