In both of these videos where he's tried to reinforce the idea that he'd be a good dad, his only point of reference is if the kid doesn't like food he gives them, he'd change it in some way. Pretty sure there's substantially more that goes into parenthood than turning their wheat thins into some kind of sriracha mayo nachos abomination and toasting their sandwiches. As with all things with Lucas though, the selling point always has something to do with food or the provision of it.
Here's a counter point to why you'd be a good dad Lucas, you can't have legal custody of a child if you can't put a fucking roof over their head. Know how you like to brag about living in a homeless shelter like it's a noble cause? Yea the federal government doesn't see it that way when it comes to raising a kid.
