Mai's Mistaken for Pregnant moment. Just as hilarious is Mea's explanation as to why she can't be: it's the wrong time of the month.

Mai: How does she know that?

In the obligatory bath scene of episode 7, Ai ends up lost in thought over her kiss with Keith while cleaning Mii. This results in her being covered in froth, and promptly running away to wash it off. It's so typically Ai that one can't help but laugh.
In the last episode, when Mai has returned to Konami's time period, the latter keeps asking the former why she's changed so much. Mai tells her it's because she's an alien. Apparently Konami found it funny too.
