Rick and Morty
S2E4: Total Rickall
These parasites are like bed bugs,
and every flashback is another mattress. Look!
There's only supposed to be six people in this house.
But there's always been 10.
Uh, the fact that I wrote this number down means that there's four parasites.
You sure about that, Rick?
Begging your pardon, master Rick,
but I seem to recall a great deal of confusion surrounding that number.
