This one you can see in Raiders of the Lost Ark if you are very coordinated with the pause button on the remote control. On the pillar next to Indy when he and Sallah open up the cement box holding the Covenant of the Ark you can see a small hieroglyphic of R2-D2 and C-3PO.
In The Temple of Doom the nightclub where Willie Scott is performing and Indiana Jones gets poisoned is called Club Obi-Wan in honor of Star Wars character Obi-Wan Kenobi.
