What are some funny things your newborn does?

My 4 week old baby girl makes cute little snorting noises! And shes pretty mellow most of the time but when shes hungry and I put a bottle or pacifier in her mouth she makes a mean face and snaps at it (imagine a cobra snapping to eat its prey lmao) or she shakes her head vigorously back and forth. Does anyone elses baby do that?
