LOL'ing-Up Project Euler One
Same Guy, Same Language, same criticism?
Let me start by (again) critzising your variable casing choice of SHOUTCASE
It's so darn hard to tell what's a variable and what's not :(
But your names got better since the last time. Cheez and Burgr aren't the best, but given their content is arbitrarily set and accordingly somewhat meaningless they really stand their ground.
One thing though: your Cheezburgers are not needed.
It's a waste of computation power to check divisors by the biggest one first if you return early. (I recall rolfl having some nice stats on that in one fizz-buzz review I can't find right now). We can completely elimimate that O RLY? YA RLY from your code.
Oh and while we're at cheeseburgers... There's one thing I really dislike on cheeseburgers... Pickles.
The temporary TROOF variable to remove that three YA RLY doing the same thing is completely overkill. Instead of PICKLES R WIN it would be sufficient to add the current Number to the total.
Code until now:
IM IN YR Mind UPPIN YR Number TIL BOTH SAEM Number AN Limit   
    BOTH SAEM 0 AN MOD OF Number AN Cheez
    O RLY?, YA RLY
          Total R I IZ AddToTotal YR Number MKAY
    NO WAI
          BOTH SAEM 0 AN MOD OF Number AN Burger
          O RLY?, YA RLY
                Total R I IZ AddToTotal YR Number MKAY
          OIC
    OIC
IM OUTTA YR Mind

Now what have we got here? this looks like it should be either an ElseIf or just a simple combination of conditions into an Or.
The latter is the easier one, but for reference: There is an else if. It's MEBBE
Final Code:
HAI 1.2
    VISIBLE &quot;HAI, PROJEK LOLLER ONE!!&quot;

    I HAS A Limit ITZ 1000
    I HAS A Total ITZ 0
    I HAS A Cheez ITZ 3
    I HAS A Burger ITZ 5

    HOW IZ I AddToTotal YR Value
        I HAS A Result ITZ SUM OF Value AN Total
        FOUND YR Result
    IF U SAY SO


    BTW Iterates from 0 to 999
    IM IN YR Mind UPPIN YR Number TIL BOTH SAEM Number AN Limit
        EITHER OF BOTH SAEM 0 MOD OF Number AN Cheez AN BOTH SAEM 0 MOD OF Number AN Burger
        O RLY?, YA RLY
             Total R I IZ AddToTotal YR Number MKAY
        OIC
    IM OUTTA YR Mind

    VISIBLE SMOOSH &quot;TEH ANSWER IZ &quot; AN Total MKAY
    VISIBLE &quot;DOWN WITH PROJEK LOLLER ONE!&quot;

KTHXBYE
