Sometimes you need to make fun of the people who are too tall.
In my language, we have a term that is used to make fun of tall people. For example we want to take a picture and a tall person stands in front. We say something like this:
Look at that giraffe! He is blocking all of us.
I know that vertically challenged is a funny and sometimes euphemistic way of referring to someone who is short.
Is there a funny idiom that can be used to refer to someone tall?
*lanky does not fit the bill

Daddy looooong legs.
beanpole
Long drink of water for someone who is both tall and slender.
I am not a teacher.
Is that common in American English? I found this quote from a movie:
All right, you scrawny beanpoles: becoming a cop is *not* something that happens overnight. It takes one solid weekend of training to get that badge.
