how you pronounce theatre without spitting????

i ask you how can't you??? i just tried all possible ways and nothings comes out except the sound of the word.... what i do to over come such probs is to take my dictionary, find the word and try to pronounce it by following those wierd symbols next to it taking help from the key at the begining of the dictionary... then try to use it as much as possible in daily speech.. that might make way for improvement...

Take a speech therapy class for your lateral lisp.
