Terror of the Girly-eyes Measles (乙女ばしかの恐怖, Hāto o tsukame?) is the 9th OVA of Urusei Yatsura.
Ten has the measles and is trying to stay away from Lum who wants to give him a shot with a very big syringe. Because Ten may have given the measles to Ataru she wants to give him a shot too. Ataru runs away, not knowing that he's carrying the alien "girly-eyes" measles strain, which gives men big cute anime-girl eyes. Now Ataru has girly-eyes and can't pick up girls without scaring them away. What's worse is that Ataru is spreading the disease all over town. Try to imagine Cherry, Onsen-Mark, Ryuunosuke's Father and the Principal with girly eyes. It's not a sight for the faint-hearted.
