Hot Thermos

One day a little old lady wanders into a nearby Adult products store. As she's wandering around, the salesclerk asks if he could be of assistance. The Lady approaches the counter and asks the clerk, "what's that white thing in the display." The clerk responds, Maam, that's a dildo, its used for personal pleasure, it's our standard model and it costs $20." The Lady says, "fine, I'll take it." So the clerk rings up the purchase and the Little old lady leaves. The next day, she's in the store again. Approaching the counter she asks the clerk, "how much is that big black one in the display?" The Clerk responds, "well Maam, that's our Super Deluxe model and it costs $40." She says, "fine, I'll take it." The Clerk rings up the purchase and the lady leaves. The following day, the Clerk notices the little old lady is back again. He asks her, "excuse me Maam, were you satisfied with your recent purchases?" She again approaches the counter and says, "oh yes, thank you." She then asks, "How much is the big plaid one on the counter here?" The Clerk tells her, "Well Maam, that's our Super Super Deluxe model and consequently it's much more expensive, it costs $80." Again the lady says, "fine, I'll take it." The Clerk rings up her purchase and she leaves. Just then, the Boss comes walking in and asks the Clerk, "what you been doing all week, goofing off I suppose?" The Clerk tells him, "no, I've had a good week, I sold a standard size dildo day before yesterday, I sold a Super Deluxe model yesterday, and hell, I just sold your Thermos bottle for $80."
