Poor Timing

Alright, listen up, not-so-smart human! This ain't rocket science, even for a bear like me. You got three things: a burnt pizza, a cold beer (which, let's be honest, could also be a warm beer if you missed the fridge!), and a pregnant woman. The joke is all about the phrase "pull it out in time." You see, with the pizza, if you don't "pull it out" of the oven when it's ready, it burns. With the beer, if you don't "pull it out" (to drink it, perhaps, before it gets too cold or before the party's over), well, you know. And for the pregnant woman, the phrase "pull out" refers to a, uh, birth control method, or rather, the *failure* of one. If you don't "pull out" during sex, you might end up with a baby. So, the common thread is a lack of timely action with a common, *ahem*, "pull out" action, leading to an undesired outcome. Get it now, smarty pants?
