(Carl's Bugly Yinny Song
Carl: Bugly Yinny! She's so ugly, she'll make you scream like a creepy monster in a scary dream! She's Bugly Yinny!
Yang: Yin, these kids are our friends! We can't just whale on them! (Hits Roger Jr.) Except for that kid, I'm kind of on-again off-again on him. We have to exerc...we have to exer...we have to ex...(Yin pats him on the back, Yang coughs)...We have to exercise self-control! Man, that's hard to get out!
Yang referring to Roger Jr.: Man, that Skelewog kid hits like a girl! (Sees Smoke) Did I just say that uncool stereotype out loud?!
Ultimoose: Get ready for some serene violence!
Yin: That's an oxymoron.
Yang and Ultimoose: What'd you just call me?
Newscaster: And now, back to our live bugly watch.
(Carl appears and glances at cameraman)
Cameraman: Do something, bugly. (Carl zaps him)
Carl: Great, it's in hi-definition, so you can see the BLEMISH!
Yang: So, let me get this straight. You defeated Carl, made him cry, and came up with the hurtful new nickname "bugly"?
Yin: I guess so. (Yang leaves and returns with a graduation cap, placing it on Yin's head)
Yang: Oh, congratulations! Today, you have graduated to complete jerkdom! (hugs Yin) I'm so proud!
Carl: Pink is so last season. It should never be worn after Labor Day... or the age of SIX!

The Powerpuff Girls: The plot for Control Issues is similar to the episode segment of Tough Love in which a villain tries to use mind control in order to force the hero's to fight against their friends.

The Grim Adventure's of Billy and Mandy: At various points during the episode segment A Bad Case of the Buglies, the look of the animation changes to show how bugly Yin and Yang look. This is a reference to a technique used many times on the formerly long-running popular show on Cartoon Network.
