Nope, I've done this before, pushed when everyone folded to me in LP with a crappy hand, then get AK and do it again with a limper and everyone folds, then 2 limpers and push again with AA, and someone calls with K3o because "I was raising with anything". Good way to double up on a premium hand but its one of those cases that the cards just have to fall right for it to work very well. Sometimes they will call you on the second push in a row, and since you pushed a few other times, a regular raise would look suspicious to some, and a limp is certainly not right.
