Biological Type Puns

So my sister is in grade 11, and on a car ride to her game she was asking myself and my parents some questions about her biology course. At one point she asked if we remembered what the two types of cells were, as she could only remember one, the eukaryotes.

Immediately after saying this, my mom chimed in with "if one is eukaryotes, then the other must be eu-dine-in's". Everybody groaned, but I'm fairly certain my dad was very proud in that moment.
