yeah, well i do 300lb curls in pretty strict form for 5 reps (5th assisted). in fact i USED to do em all the time. there WAS a guy that saw me do em but he's deceased now so...
i've got 3 lines of proof
1. i USED to do em all the time so i can't show you now.
2. i'm saying i did them on the internet
3. if you don't believe me you're a skinny little girlie boy that's never trained in a gym.
4. the only person that saw me do them all the time is dead. i trained in the busiest and most popular gyms in america with 98567020 hardcore strong motha fukas and they all saw me do every other lift that i did and can tell you exactly how much weight i used in all those other lifts (just ask em), but.............i only ever trained arms in front of one person and he's dead so you are a fuking puny little nobody if you don't believe me.

5. did i mention you're a skinny little girlie boy if you don't believe me?
