* When Igor is trying to teach Duckula about his ancestors:
--> '''Duckula:''' "I don't want to hear about my forebears, my three bears, Goldilocks or anything else in this rottendreary hole!"
* When Duckula's computer messes with some numbers at the bank we see an old lady checking her balance. The teller reads (mistakenly) that she is worth ten million Drachmas.
--> "Ten million! Marry me, you temptress. You vixen of desire."
* In "No Yaks Please We're Tibetan", Ruffles' gang of thieves are climbing up a mountain in the Himalayas, planning to steal a huge collection of yakhair carpets and sell them for a fortune in the department stores of Europe and America.
-->'''Burt:''' Er, boss?\\
'''Ruffles:''' ''(to himself, frustrated)'' I don't believe it... ''(to Burt)'' What now!?\\
'''Burt:''' Erm... wot's a yak?\\
'''Ruffles:''' ''(standing on a ledge while the other thieves hang on a rope over the edge, oblivious to the huge yak standing right behind him)'' "Wot's a yak," he says! A yak is a great fat stupid 'airy great cow wot grows in Tibet. Now, 'ave you got any more stupid questions!?\\
'''Burt:''' Er... no, boss.\\
'''Ruffles:''' Good! ''(the yak steps on Burt's fingers)''\\
'''Burt:''' Well, just a little one.\\
'''Ruffles:''' Oh, ''Gordon Bennett''... WHAT!?\\
'''Burt:''' Well, it's just, er, could you get your boot off my fingers?\\
''(Ruffles groans in frustration; the yak steps off Burt's fingers)''\\
'''Burt:''' Oh, thank you, boss. ''(he lets go of the ledge; gravity kicks in, and the four thieves plummet down the mountainside, landing with their usual "three thuds, short pause, fourth thud")''
* The entire [[WhosOnFirst Hoomite Yubi]] sequence from the first episode' "No Sax Please We're Egyptian". Especially Duckula's SanitySlippage at the end, when Nanny shows up and it looks like the whole thing is starting over again.
-->''(we see a blurred shot of Hoomite through Duckula's eyes)''\\
'''Hoomite:''' He's coming round!\\
'''Duckula:''' ''(groans and sits up)'' Oh... where am I?\\
'''Hoomite:''' You are in the secret temple of the great god Ra! You have trespassed in Upshi's sacred tomb!\\
'''Duckula:''' Oh. Oh no. Who are you?\\
'''Hoomite:''' I am Hoomite, high priest of the great god Ra. And this is my assistant Yubi.\\
'''Yubi:''' Delighted, I'm sure.\\
'''Duckula:''' Ah. Hello.\\
'''Hoomite:''' Who might you be?\\
'''Duckula:''' Yes, I got that.\\
'''Hoomite:''' No, who might you be?\\
'''Duckula:''' Yes, I know, I know, you said that already.\\
'''Hoomite:''' ''(glaring at Duckula)'' So you will not tell me?\\
'''Duckula:''' Well, I hardly need to, do I?\\
'''Hoomite:''' We shall see about that! Yubi, you try.\\
'''Yubi:''' Oh, very well, Master. ''(clears throat)'' Listen. I am Yubi, right?\\
'''Duckula:''' No, ''wrong''. "I am", "you ''are''".\\
'''Yubi:''' Ah! There Master, he is Yuarr!\\
'''Hoomite:''' So you are Yuarr?\\
'''Duckula:''' I am not, I am not!\\
'''Hoomite:''' Ah, you are Nott! He is not Yuarr, he is Nott!\\
'''Yubi:''' You ''are'' Yuarr!\\
'''Duckula:''' ''(waving his hands in a negative gesture)'' I am ''not'' Yuarr!\\
'''Yubi:''' Oh, call me not Yuarr! I am not Yuarr, I am not Nott! I am Yubi!\\
'''Duckula:''' ''(clears his throat)'' Let us get this sorted out! Okay? I am ''not'' Nott, okay?\\
'''Hoomite, Yubi:''' Okay.\\
'''Duckula:''' I am ''not'' Yuarr! Okay?\\
'''Hoomite, Yubi:''' Okay.\\
'''Duckula:''' ''(pointing)'' But you are Hoomite, ''(Hoomite nods)'' and you are Yubi, okay?\\
'''Hoomite, Yubi:''' Okay.\\
'''Duckula:''' Whew.\\
'''Hoomite:''' But...\\
'''Duckula:''' ''(impatiently)'' Yes?\\
'''Hoomite:''' Who might you be?\\
'''Duckula:''' ''(begins sobbing and gibbering)'' I can't stand, I can't stand anymore!
* The RunningGag in the first episode where the Crow Burglars keep getting hurt, with four distinct thuds being heard each time.
* Igor's nauseating TastesLikeDiabetes personality after getting doused with Von Goosewings personality altering chemicals. In that same episode, Duckula being transformed into a traditional vampire in the same manner.
** Even funnier is that Goosewing intended for the chemicals to turn Duckula into a non-vampire, but it instead did the opposite.
* Igor's hatred of Duckulas harmonica, which he hides at every opportunity
* From "The Mutinous Penguins": "[[ItMakesSenseInContext Tie 'em to the comfy sofa]]!"
* Igor's worst nightmare in "The Zombie Awakes!": being surrounded by cute and cuddly bunnies.
* Igor's attempts in getting rid of the engaged couple in "Igor's Busy Day", all ending in epic failure. Mostly due to Nanny's incompetence.
* In "The Lost Valley", Nanny knocking out a dinosaur with just a single jab in the stomach and then scolding it as if it was a child.
* From the comics, Igor commenting upon Duckula's latest ambition: "A vampire casts no reflection; neither can his image be captured on film. A slight impediment to a career as a movie star."
* In "Unreal Estate", Igor tries to sabotage Duckula's plans repeatedly. It backfires about as much as you'd expect.
