* Professor Abronsius is one of the funniest characters in the entire musical. Half of his lines, as well as his tendency to [[LargeHam ham things up]] make him utterly hilarious. Here are a few examples to prove it.
** When Professor Abronsius and Alfred are in the Count's castle, the Professor stumbles upon a whole load of books. He then proceeds to sing a [[LongList song with lyrics that consist almost completely of authors]]. At first, Alfred wants to talk the professor out of it. Failing to do so, he leaves and the plot continues for quite some time with them apart. He finds Sarah, and they have a duet (Which is mostly about Sarah [[spoiler: not wanting to leave]]), and Alfred songs a solo number while returning to the professor. When they meet again, Alfred gets his song interrupted by the professor... who is STILL singing authors.
** During "Sie irren, Professor" (the reprise of "He, Ho, He"), he uses a proper mad professor threat: "You underestimate science, von Krolock! I will pickle you in alcohol and add you to my collection."
** The unexpected and incredibly high note the Professor hits during "Wahrheit" is hilarious as well as awesome. So is the rest of the song.
* The GIGANTIC sponge Sarah whips out in the bath scene in the castle - to show Alfred how well the Count treats her.
* Koukol trying to get Chagal and Magda out of the castle's crypt.
* "That doesn't work on me! I'm a Jewish vampire!"
* All vampires scream and draw back when they see the cross. Herbert faints, which is similar to Alfred fainting when [[spoiler: Sarah gets bitten]].
* The Professor getting clobbered by Rebecca when she mistakes him for her husband.
* Alfred and Herbert's "Wenn Liebe in dir ist" duet.
** Somehow even more hilarious when the roles are switched, as in when Lukas Perman (Alfred) and Marc Liebisch (Herbert) decided to swap costumes. [[https://www.youtube.com/watch?v=ec98Jqf6tJU Enjoy.]]
* "Die Gruft" is already funny as it is, but during an open day at the theater in Berlin, Sven Prüwer (Abronsius) and Dennis Jankowiak (Alfred) decided to sing that with an appropriate Berlin dialect, to the audiences tremendous delight.
* A classic example of Professor Abronsius' NeverMyFault attitude: The Professor and Alfred are trying to sneak down to stake Chagall. Abronsius takes one step, the old floorboard groans under his weight, Abronsius hushes Alfred. He takes another step, again the floorboard groans and again he motions Alfred to be silent. When the floorboard groans ''again'' under the third step, Abronsius gives his assistant an exasperated look. Alfred meanwhile hasn't made a single move the entire time.
* Count von Krolock, of all people, gets one funny moment as well. The Count gets a bit caught up in the moment when singing about eternal sadness. He pauses, than turns around - to see Alfred and Professor Abronsius bored out of their minds and nearly asleep. Depending on the actor, the reaction to that varies. Sometimes the Count scares them with a "Boo!", sometimes he starts laughing ([[BreadEggsBreadedEggs and sometimes both]]) and sometimes he has completley forgotten about his visitors and looks entirely puzzled when he sees them.
* Jan Ammann is fond of adding his owns sense of humour when portraying the Count. In "Vor dem Schloss" he gives us this gem:
--> '''Count von Krolock:''' ''The'' Professor Abronsius?
--> '''Professor Abronsius''' ''(flattered)'': You have heard about me?
--> '''Count von Krolock:''' I read your book "The Bat". ''Brilliant''! [completeley [[DeadpanSnarker deadpan]] and bored] I was enraptured.
* Alfred's enraptured face as the Count sings to him in "Vor dem Schloß" (for example, Anton Zetterholm's dazed - almost ''gormless'' in an adorable way - expression). It's HoYay and funny at the same time.
* Darkly funny, given what just happened, but Raphael Groß's utterly delighted-sounding, if not ''gleeful'', "Not bad!" after [[spoiler: vampire!Alfred had his first taste of blood.]]
