In an issue of X-Factor V3, Rictor is being questioned by the police about a contact. He finally gives up the name "Robert", describing him as having a pointy nose, a rectangular face, wide eyes, and yellowish skin. The cop comments that "Robert" sounds like a druggie, and the other guy agrees, saying he claims to live under the sea... in a pineapple. The cop remains clueless (and another one, upon finding out, pegs him as not having any kids and gripes that now that song is going to stick in her head all day).
In X-Factor 213 V3, Madrox is reaching to open the door saying at least they didn't bring Pip with them (after they teleported and left him in Vegas), *SLAM!* Pip slams the door on Madrox's face from the other side and quips that he can teleport too.
