Though sometimes criticized for casting similar stereotypical roles every season or so, each cast does have something to set it apart from the others--and hopefully keep viewers watching.

In this video, all the intros up to the fifteenth season are played.

It may interesting to note the progression (or regression?) from the original cast to the more recent casts--or even just the differences in fashion from the 90s!

Note: The video does not begin until 00:37. My apologies for the delay.
