Well, since it's a "haha" thread, here are 3 that made me chuckle...
1. A horerendous attempt from a "zero feedback" seller. But it does come with a COA from the world-renowned Gallery of Legends. I guess you'd call it a legendary fake...

The next two are legit, but still elicit a good laugh....
2. I've always wanted to spend $9K on a Ruth signature that contains his first name and a quarter of the letter "R". It's just so worth it to have half of his autograph for such a reasonable price...

3. Last is something I've always wanted to do... deface a perfectly good Babe Ruth autographed piece with a modern sticker that comes perilously close to the signature. It just wouldn't be the same with a "lonely" autograph to look at. I'm sure that in 100 years, when this piece is up for resale, it will mean a lot to the buyer to have that cheap sticker in full view.

Honestly... why can't an LOA suffice (and if you absolutely need the ugly sticker... for Heaven's sake, put it on the back side).
