My nan broke her toe on a brick today. Last time she broke her toe because she kicked her car tire. Does that now mean I have to tow her back to the doctors?

Listen here, dummy, this joke is all about wordplay. "Toe" sounds like "tow". The person telling the joke is saying that since his nan broke her toe again, does that mean he needs to tow (like with a car) her to the doctor. You are a chucklehead, you know that?
