Elementary’s intro had great music and a nice sequence.
House MD (mostly for the non-Teardrop music version)
Swat Kats
Dexter’s Laboratory
Batman: The Animated Series
The Triumverate.
First because I could listen to Jeremy Irons read the phone book, and second because each intro is funny and unique.

What We Do In The Shadows
Sopranos
Peacemaker
Cowboy Bebop
Broad City (haha)
Woke up this morning, got yourself a gun.
