See, I don't read it as being sexist. I read it as being a joke/jab at the fact that that model must have taken WEEKS, maybe even MONTHS, to build--it's gotta have several THOUSAND pieces in it and it's nearly as tall as he is. It's poking fun and saying, 'Daaayum, have you done ANYTHING ELSE since January??' Aka, you have a lot of time on your hands and probably didn't spend it talking to potential mates.
