Unsure whether they qualify, but there are some fun facts taken from various sources:

Beginning from Yann Lecun:

• Geoff Hinton doesn't need to make hidden units. They hide by themselves when he approaches.

• Geoff Hinton doesn't disagree with you, he contrastively diverges

• Shakespeare and Bayes are in a boat, fishing. Bayes is trying to figure out which net to cast when Shakespeare says: "loopy or not loopy? that is the question".

• Deep Belief Nets actually believe deeply in Geoff Hinton.

• Geoff Hinton discovered how the brain really works. Once a year for
  the last 25 years.

• Bayesians are the only people who can feel marginalized after being integrated

P.S: Ian Goodfellow and Jurgen Schmidhuber are co-authoring a paper (to be presented at NIPS 2019) on Inverse GANs (More jokes on the topic here)
