Peter: A Job? Lois the seventies are over, forget it.

Cat in the Hat: Your parents will be home any minute, are you sure you don't want me to clean the place up?
Young Peter: No, no, go... it'll be funny.

Lois: A flight attendant? Wow, that does sound exciting. What made you change your mind?

Stewie: Duck, duck, (slaps Janet on the head) GOOSE!
(Janet cries)
Stewie: Oh come on I barely hit you! See this is why people don't respect the WNBA!

Peter: Wait, wait, wait, wait a second. You're tellin' me that I came all the way to Kentucky to get some of your fried chicken, and the Colonel isn't even workin' today?!?

While Peter and Lois are floating back to America from Cuba, Lois says they are floating somewhere in the Atlantic. However, this is geographically impossible. They would have to be in either the Carribean or the Gulf of Mexico.

The blocks Stewie is playing with change between shots.
When we read “My Lovely Janet”, the red “M” on the top tier has a moon on its side, the purple “L” in the 2nd tier has a star on its side & the red “J” on the bottom has nothing

but

When we see the blocks from the back, the red “M” has a sideways 6 or 9, the purple “L” has a basketball & the red “J” has a star.

Also, when Stewie knocks the blocks & they spell “I Long For You” & “Ride That Pony” all the designs on the other sides are gone but reappear when seen from afar.

When we see Kurt Cobain on stage from afar, the hole in his jeans is in the left pant leg but when we see him up close & backstage the hole is in the right leg.

In the wide shot of the kids at nap time, we see there's a girl napping to Janet's left (our right), but when Stewie crawls to her the girl is missing & when Stewie crawls away to get Janet a cookie, the girl is back on her mat.

Also...

In the wide shot, Janet is napping on her left side but when Stewie looks back, she's suddenly asleep on her right side.

Stewie crawls back to his mat to get Janet some Animal Crackers when he didn't have any when he was talking to Leonard

In the wide shot of the kids at nap time there's a girl w/ dark pink shorts and light pink shirt sleeping above Stewie however when Stewie crawls to Janet the girl has been replaced by the boy in an orange shirt and green pants who was napping to the right of Leonard in the wide shot.

The child is missing completely when Stewie turns and says “You don't care about me” and the girl in the pink is back when Stewie storms off.
