simplest complex sentence

well , can u tell me the simplest complex sentence , i asked the question to my friend , he replied as "i" ..duh .. what ?? yes it is ..The "i"in the complex number a+ib the simplest number must be 0+i1 which is equivalent to "i" . so it is the simplest complex number . I felt like chasing him down the streets and killing him with an evil smile .. But one way he is correct "i" is the complex word as what i mean by I .
who am I ? what is called as "i" .Is it my legs, my ears, my eyes etc.etc ..oh it is the integral of all these right ? Then cant i call myself as i if i lose my legs, my ears , my eyes etc ..
some one said when u realise the real meaning of "i" u will lose your "i" . Really who am i ? i is a relative word , i am a good person to "x" if i helped X and i am a bad guy if i done something bad to him and after all i am a relative term to myself i.e., if i feel good compared to some of the rules i have framed in my mind then i will call myself as good guy . i will be a giant if i am in the land of lilliput or else i will be a dwarf if am among the inhibants of brobdingnag (if is spell correct )....
sigh ..no more analysis let me come back to the old question it is not going to do anything with the grammar "complex " and compaound sentence but something like this .. the simplest sentest i know is
"I am a liar "
1) if this sentence is true then i am a liar but these words are said by me so i must be lying this means that i am not a liar ..
2) if this sentence is false then i am not a liar but saying this i have lied ...

confused ?? well working on some other sentence...
