I saw a movie theater sign where someone had rearranged letters, turning “A Star is Born” into “A Rat is Born.”
I also saw a sign that said “Lot for Sale.” One day someone removed the L from lot and replaced it with a P.
This thread makes me think about “Fawlty Towers”. Remember how the sign would always be changed around at the beginning of the show? I think my favorite one was “Twatty Flowers”. 
There was a Shell gas station in a little town near my hometown. The “S” burned out, so for a while, when the sign was lit up at night it said “Hell”. My father always liked that one. He’d say, “See, I told you there was a Hell!”
There are quite a lot of musical Jews out there. Here’s one on eBay Philippines.
Not quite what was asked for, but this always gives me a laugh.
On a main road near where I live is a big sign for a Pain and Neurology Clinic.
It’s next to a tattoo palour.
Even better was “Flowery Twats.”
Damnit! Something’s gotta be done about this new musical Jew trade. For crying out loud, just because they’re talented doesn’t mean they should be stuffed in a box and mass marketed! It’s shameful. Shameful!
Sorry. I’m getting a little verklempt.
It was corrected in a few days, but yeah, it was funny. Usually the typos occur in the player’s name, not the teams.
There was a car wash on Newport Blvd here (very high traffic) that called itself “The Hand Job.” Swear to God.
I remember I once saw a lighted sign for a pet store (probably Petco) that was supposed to say “SUPPLIES AND FISH” but the “SUPP” had burned out, so apparently the store dealt in “LIES AND FISH.”
That reminds me of a sign I read in a NatLamp “True Facts Signs” book. It was for a real-estate company, featuring the bottom half of a man with his pants dropped, surrounded by the words “We beat our competitor’s [man-with-dropped-pants] off.”
Of course, ignoring the pantsed guy, or not realizing the he was part of a simplistic rhebus, yielded an unfortunate result…
I regularly drive past a warehouse on Sepulveda that advertises “Elf Storage”.
A Hollywood Video franchise here had the lights out in the third through fifth letters of its sign. I wonder if they got more business when they were HO WOOD VIDEO.
Also, the MUNI turnstiles in San Francisco used to have LEDs which spelled out “PASS OR $1”. One time I was about to go through one at the Castro Street station and noticed that the letter P was out. I elected to pay the dollar.
An electronics shop in Toronto had presumably once sold TAPES, but by the time I saw it, it had branched out to APES.
For a while in Massachusetts it was considered hysterically funny to steal the “S” from the local “POST OFFICE” signs.
