Telephone icons always seem to use the same Bell 1960s-style handset. The last time I saw one of those was in an old movie.
Gas pump icons have the tombstone, side-hose design. I haven't seen a pump like that in 10 years either.
Hourglass cursors to mean "thinking, please wait" don't make any sense either. A rainbow beach ball isn't much better, but at least it's a little more abstract.
