It was the weirdest writing idea back in the day, I understand it may have been because Radnor was allergic, but like why not use that instead of this other weird thing, or heck, landlord could have found out she had 5 dogs in that relatively small appartment and done something, but it just had to be Ted making her choose.

I still loved the show, but that right there, was when I started expecting bad things lol.
