Is there any fun bass lines to play to show off between songs or sets?

depends on your ability... also what sort of gigs are you playing to who?

i find just throwing in a few improve slap bits while a guitarist retunes/a singer warms up the audience never goes down badly. Maybe just play a quick couple of bars of the chicken or if you want to show off portrait of tracy. Pro tip: well known = more appreciated...
Learn to counterpoint and improvise in the fills (spaces between a lead instruments phrasing). When you do this with a lead instrument, jazz crowds go nuts.
