Bubbles has learned an important survival lesson about the apartment today: When Pintsize does something weird (which is more often than not), don't mention it and certainly don't try to engage with him. Just shake your head and walk away. Seriously, your day will be better for it.
Now... Is Pintsize...
jealous here? Is Jeph drawing a parallel with
yesterday's strip? Or is this another one of those times when Pintsize uses his random behaviour to try to help someone? After all, it is arguable that Bubbles
is overcompensating but there's no-way to tell her this without offending her. If, instead, you mention it whilst doing something weird, it gets into her brain without having to say it in the context you intended!
Yes, I'm a believer in Pintsize being a hidden psychological genius as well as being serious about his contract duty to help his apartment-mates.
