This not a Meme but the spectral view of "Barcode Brothers - Tele" a song from 2008, how many DTMF code tones can you find?

Here's a fun one:
Aphex Twin / ΔMi−1 = −∂Σn=1NDi[n][Σj∈C{i}Fji[n − 1] + Fexti[[n−1]]

Here have some more
DTMF (with examples): https://www.sigidwiki.com/wiki/Dual_Tone_Multi_Frequency_(DTMF)
Decoder options: https://github.com/EliasOenal/multimon-ng https://www.w1hkj.org/files/fldigi/
Or decode by hand using a Spectral display, in some cases other audio effects can negatively impact the precision of automated detection.
