The Dave's not here routine comes from comedy duo Cheech and Chong, whose stoner humour made the exchange a widely quoted catchphrase long before short video and meme culture picked it up. In the routine, a visitor keeps asking for Dave while the person answering insists, in increasingly deadpan fashion, that Dave is not there. Shared as a short audio clip, it survives because the situation is instantly familiar: avoiding a call, a visitor or an awkward conversation. Its short length also makes it easy to reuse as a reaction punchline.
